1.Invention and Development of POLIYOU^®:

From its spelling one readies it is related to Polyurethane．Yes, it is l00% a product made of Mr. Chang Kun-Huang and co-workers started the Revolutionary task of material science in 1981.After numerous Studies, research work, and tests, the first pioneer product was successfully made in l984, It was a revolutionary breakthrough in chemical reactions．

Mr. Chang，after decades of experience, had successfully applied catalyst to foaming process Which resulted in highly dense, porous and ventilate product, which eliminated major Problems traditional PU foams had﹒

2.Characteristics of POLIYOU^® Material:

The material of POLIYOU^® is superior or than traditional PU due to its Breakthrough in foaming process. It is of greater physical quality and more stable chemical property; it has the following structural advantages:

a) Open cell structure which achieves 95% ventilating effectiveness．

b) Superior moisture absorbing ability than similar material; more over, the structure maximizes the drying ability．

c) Elimination of growing environment for molds of athlete foot which provides a more comfortable wearing feeling．

d) Owing to hardness difference, the material loss in thickness for POLIYOU^® is 14-25% in comparison to 35%-54% for EVA and 50%-60% for polyethylene foam．

e) Conditions during shaping for POLIYOU^® material is unique, which，after shaped, is hard to transform subject to external forces．

f) Unique absorption of ammonia excellent Anti-fungus, Anti-Bacteria abilities that greatly increases de-ordering capability．

g) Various hardness can be achieved to meet customer requirements which is impossible for traditional PU foams．

h) Stability: Excellent stability to heat; no property 250^oC, good for long-term storage.

i) Process ability: Easy to be processed done, or with other material
