PU Foam for Shoes Insole
UV stability plays a very important role,where paling (yellowing) is detrimental to the product quality ,outlook and life.
Paling is natural process caused due to oxidation which is a result of combined action of oxygen and light ,especially UV light .This foam has no carbon or any other auxiliary blowing agents .This makes the foam usable in various kinds of undergarments,without harming the human body .This speciality foam provides superior thermo-formability and color stability .It has a high stability to light ,obtained by means of special additives .It is environment friendly and meets ROHS and REACH standards.
The most critical aspects of UV stable foam are Hydrolysis Test ans Sun Test ( Color Fading).Resistance to light is evaluated on a weatherometer and is expressed in terms of number of hours of exposure under xenon lamp that is considered necessary to reach a certain degradation or color fading and is measured on Grey Scale Index of 1 to 5 depending upon the products and customer requirements.
