The elastic strength of plastic ziplock bags

Plastic ziplock bag polyurethane thermoelastomers have a higher tear strength, usually up to 10 times that of natural rubber. However, the high temperature resistance is poor, and the ambient temperature is higher than the energy. In terms of electrical properties, polyurethane thermoelastomers have certain hydrophilic properties, absorbing less moisture from the air and reducing the insulating properties. The use of thermoplastic elastomers in highly insulating applications is limited, except for diene. In most cases, the raw materials used for injection molding are virgin. However, for some products with low use requirements, people often use recycled raw materials for injection molding. On the one hand, it can reduce costs; On the other hand, it is possible to realize the recycling of plastic materials.
