The difference between plastic and rubber

　　Chemical composition. Plastics are mainly made of synthetic polymer materials, such as polymers, copolymers, etc., whose basic components are elements such as carbon, hydrogen, oxygen, etc; Rubber is a material made by mixing natural or synthetic rubber resin with various additives (such as vulcanizing agents, accelerators, anti-aging agents, etc.), and its basic components are carbon, hydrogen, oxygen, sulfur, and other elements.

　　Physical properties. Plastic is usually harder, more transparent, and has fewer defects than rubber; Rubber is relatively soft, with good elasticity and stretchability.

　　Manufacturing raw materials. Plastics are mainly made from petrochemical raw materials such as oil and natural gas, and are obtained through polymerization reactions; Rubber is mainly a polymer synthetic material extracted from natural rubber trees or synthetic rubber raw materials.

　　Application field. Plastic products are commonly used in the manufacturing of household appliances, mechanical equipment, toys, furniture, building materials, etc; Rubber products are mainly used in the manufacturing of tires, pipes, seals, etc., and are widely used in professional fields such as shock absorption, sound insulation, and shock absorption.
