| ABSTRACT |
Most of the polymeric foam is toxic, non-degradable, non-sustainable, heavily polluting and disappearing commodity such as polystyrene and polyurethane. Polystyrene and polyurethane is classified as a possible human carcinogen by the (Environment EPA and by the International Agency for Research on Cancer (IARC). For example, Isocyanates are compounds to produce polyurethane foam which is classified as potential human carcinogens and known to cause cancer in humans and animals. The main effects of hazardous exposures are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin.Therefore, it is necessary to increase the usage of environmental friendly polymer which is safe/non-harmful to human and environment.
¿PAPER-NAPP¿ is the abbreviation for new foaming polymer composites consists of recycled newspaper (RNP)/ polypropylene (PP)/ natural rubber (NR). PAPER-NAPP foam is a lamination system composed of two types or more of closed cell foams, which exhibits various foam hardness and modulus. This system is rarely found in polymeric foam materials. The foam provides outstanding compression strength of a thin sample. This special characteristic improves the dimension of foam in packaging application and cost. Moreover, the foam possesses low density, good buoyancy for flotation, withstands multiple impacts without significant damage, highly durable, resistant to water, chemicals and mostly oils, high thermal insulation with environmental benefits.
