1. Foaming Agent: Creates gas upon heating, forming bubbles that reduce density and improve insulation, used in products like shoes and flooring.

2. EVA (Ethylene Vinyl Acetate): Copolymer of ethylene and vinyl acetate, offering flexibility, toughness, and UV resistance, used in packaging, footwear, and solar cell encapsulation.

3. LLDPE (Linear Low-Density Polyethylene): Polyethylene with a linear structure and lower density, offering toughness and flexibility, used in films, pipes, and packaging.

4. LDPE (Low-Density Polyethylene): Polymer with branched structure and low density, flexible and widely used in packaging and containers.

5. HDPE (High-Density Polyethylene): Polymer with high strength-to-density ratio, offering stiffness and chemical resistance, used in pipes, bottles, and industrial applications.
