Elastic Strength Of Plastic Ziplock Bags

Polyurethane thermoelastomers for plastic ziplock bags have high tear strength, usually 10 times that of natural rubber. However, the high temperature resistance performance is poor, and the operating ambient temperature is higher than the energy. In terms of electrical properties, because the polyurethane thermoelastomer has certain hydrophilic properties, it absorbs a small amount of moisture from the air and reduces its insulation. The use of thermoplastic elastomers in high insulation applications is limited except for the aforementioned dienes. In most cases, the raw materials for injection molding are made of new materials. However, for some products with low requirements, people often use recycled raw materials for injection molding production. On the one hand, costs can be reduced; on the other hand, the recycling of plastic materials can be realized.
