High-impact materials

Most of the impact is created by providing the materials contained in the product. This includes production of waste and consumption of energy in producing the raw materials. Typical high impact materials would include rare metals, natural extracts such as perfume ingredients, and energy intensive materials such as bricks and concrete. Electronic and electrical equipment are typical of products in this category. 

ADVANTAGES AND DISADVANTAGES OF THE BLEND Ferrolene exhibits good flow and dimensional stability while being a high-impact material. TYPICAL BLEND PROPERTIES (see Table 1)... 

Calculated impact stress will often exceed ultimate stress listed in data sheets for high impact materials. 

It is necessary for the dispersed rubbery substance to have a Tg value lower than the temperature at which the high-impact material is to be used. Many elastomers will satisfy this condition they are butyl rubber, polybutadiene, SBR, BAN, ethylene-propene elastomer, polychloroprene, EVA, polyisoprene, polyacrylates, PIB, and chlorinated polyethylene (CPE) elastomers. However, they are not all useful for specific blends such as PVC-based blends because they do not fulfill the other necessary properties. 

For the production of wrapping materials, modifiers such as graft terpoly-mers of the type (methyl methacrylate)-butadiene-styrene (MBS) have been developed [89]. Some of these modifier also have the properties necessary to be used in the production of transparent and colorless PVC-based high-impact materials. The transparency of products is obtained when refractive indices of both the modifier and PVC match.
