The characteristics of the microcellular polyurethane in outsole manufacturer

      Porous polyurethane elastomer is between performance and an elastomeric foam material between the core material between the foam and the solid density of from, the cell diameter in the 0.1-10um, the aperture more evenly distributed, taking into account the foam is light, good impact resistance, energy absorption, high strength and good cushioning performance elastomers, good wear resistance advantages.

      Since the polyurethane elastomer has a two-phase micro-structure microscopically, and up to 0.6 density polyurethane soles, and its physical properties can be adjusted within a wide range depending on the formulation. Easy molding and changing varieties and models . 1.1.3 Development of microporous polyurethane microcellular polyurethane soles which are used from the late 1960s began, Western Europe since the 1970s for the production of polyurethane soles and heel shoes, because of its light weight, abrasion resistance well, have developed rapidly.

      By 2000, the total growth of the polyurethane sole material was 39.2%, while the growth of other types of sole material was 11.1% polyurethane material currently occupies an important market in the footwear industry. China is the world's first production of shoes big country, accounting for 43% of global production of polyurethane soles application market has great potential for development, shoe technology and quality has reached the level of developed countries

         Sole material, SBR / LLDPE / EVA blend foam shoes, TVA novel styrene elastomer shoe, PVU shoe, shoe made of latex foam with activated carbon and microporous polyurethane and polyether new outlook on the industry . Keywords: porous polyether polyurethane; blended; TVA; PVU.

         Foreword Chinese footwear industry sprung up everywhere, in just ten years, the world's largest producer and exporter of footwear, especially after China's accession to WTO, China's footwear industry presents a more robust development momentum, footwear production accounts the world's total of nearly 40% to 50% in the global footwear trade, China's footwear exports has accounted for 25%, both ranking first in the world. At present, China's footwear accounted for 22% of total world consumption consumption is one of the world's most important consumer of shoes .

          With the improvement of people's living standards, people are also rising demands for shoes, from the previous focus only nice, nice change to focus on at the same time, pay attention to their safety comfort. The good quality footwear sole material properties change and has a very close relationship, determines the soles of functionality and comfort. In recent years, we obviously feel as advances in production technology, the sole material has become increasingly diverse types of materials, and reflects the degree of special-growing, thus through constant development of enterprises, the new sole material has gradually emerged, provide some protection for the quality of our footwear products.

          The following soles of several new materials are discussed. 1, an overview of several new shoe 1.1 new polyether polyurethane elastomer sole microporous material advantages and disadvantages 1.1.1 polyether polyurethane liquid polyurethane soles used by the polyol can be divided into two types of polyester and polyether category. Many performance polyester soles such as tensile strength, tear strength, abrasion resistance, superior polyether soles, so far as the domestic market mainly polyester polyurethane soles. But the disadvantage of polyester polyurethane is susceptible to hydrolysis and biodegradation, sole prone to cracking, fracture; polyether polyurethane soles just to overcome the weaknesses of polyester polyurethane soles, with a strong low-temperature performance, hydrolysis resistance and mildew performance .

        While polyether polyurethane abrasion, folding relatively poor, but by examining Yantai Wanhua found with the use of a certain amount of reinforcing filler, prepared soles have improved significantly in terms of mechanical properties, wear resistance and Fold meet the actual requirements of the sole.

President Obama issued a proclamation on 3 November 2011 that implemented the recommendations of the U.S. International Trade Commission regarding the addition of an additional U.S. note and the amendment of certain classification provisions in HTSUS Chapter 64 relating to certain footwear featuring outer soles of rubber or plastic to which a layer of textile material has been added.China soccer shoe soles maker football cleats outsoles supplier China

These changes reflected decisions of the World Customs Organisation's Harmonised System Committee on the classification of that particular footwear. U.S. Customs and Border Protection has held in a series of rulings issued over the past decade that footwear with textile materials that cover over 50 percent of the external surface area of the outer sole are classified as other footwear under heading 6405 and therefore face significantly lower duties than footwear with rubber soles.

Since 3 December 2011 this footwear has been classified under one of several eight-digit breakouts within headings 6402 and 6404, which are the headings where the subject footwear would normally be classified if it did not have a textile outsole. This change was intended to be tariff neutral because footwear with textile outsoles theoretically continues to face duty rates of 7.5 percent or 12.5 percent under the new eight-digit breakouts. However, the proclamation also created an additional U.S. note (AUSN 5) that states that:

"For the purposes of determining the constituent material of the outer sole pursuant to Note 4(b) of this Chapter, no account shall be taken of textile materials which do not possess the characteristics usually required for normal use of an outer sole, including durability and strength." CBP sought input from the public on the interpretation of the phrase "characteristics usually required for normal use of an outer sole, including durability and strength" and subsequently proposed to recognise ISO 20871 in assessing the characteristics of textile material attached to outer soles.

On 13 November CBP issued a final notice in the Customs Bulletin recognising this standard, taking into account certain clarifications regarding the test's applicability and interpretation of its results. ISO 20871 is an abrasion test intended for all outer soles irrespective of material. If textile material applied to an otherwise rubber or plastic outer sole is still present on at least one of the three required samples on which the test is performed, the footwear can be classified under heading 6405.

Otherwise, the textile material will be disregarded and the footwear classified under the appropriate provision within the headings for footwear having rubber or textile outer soles. Accordingly, in order to demonstrate that the terms of AUSN 5 have been met, either as part of a request for prospective ruling, in response to a request for information via CBP Form 28, or attached to entry documentation, importers should present independent laboratory reports applying ISO 20871.

In addition, CBP may conduct its own testing by applying ISO 20871 on footwear samples when circumstances warrant. It should be noted that footwear whose only outer sole material is textile will not be subject to the new test. Most indoor footwear should also be excluded, as CBP acknowledged that the test is not likely to be useful in assessing whether textile material on the outer soles of footwear worn exclusively indoors satisfies the terms of AUSN 5. However, CBP will consider the applicability of the test to indoor footwear on a case-by-case basis.

    • As the “low-carbon, eco-friendly” trend is arousing more and more public attention, various brands in the footwear industry are launching “low carbon society” campaigns, with some of them introducing low-carbon product series featuring green raw materials, energy conservation and recyclability in a move to enhance their brand to attract consumers. Examples include low-carbon shoes, low-carbon green sports shoes, and low-carbon leisure shoes.

Silicone market to grow at rate of 6 percent

Written by


China shoe outsole supplier and manufacturer

Europe, which experienced significant downturns due to recessions in the latter part of the 2000s. The Asia-Pacific region is expected to continue to be the largest market for silicones in the world. Furst said it is projected to account for more than 40 percent of global demand on value and will be the fastest growing region. Silicone prices on average are expected to grow at a slower pace in compared to the 2007-12 period, Furst said. GDP in all world regions grew at a steady pace from 2002-07 until the onset of the global financial crisis, which Furst said triggered recessions in most parts of the world.

The notable exception was China, which continued to see double digit GDP growth even in 2009. Most economies have recovered since the recession, but Furst said it was not as big as initially projected. The sovereign debt crisis led to a double dip recession in many western European countries.

“We’re expecting a rebound to positive growth in all major (European) markets, although growth will remain the slowest of any world region” Furst said. “Because of the continued economic weakness in 2013, our previous growth forecast might be tempered to some extent.” Through 2017, Furst projects that global GDP will grow by 4 percent per year and most world regions will return to the normal growth since prior to the recession. China and India are two markets to watch as Furst labeled them as the world’s fastest growing silicone economies, even if the growth will be tempered over the next five years. “The silicone market in China will rise at a slower rate, more closely following GDP,”

Furst said. “However, China will remain the world’s fastest growing silicone market and will overtake the U.S. as the world’s largest consumer of silicones in valued terms.”
