What plastic is good for UV resistance? Here are ten types of plastics that are better at UV and weather resistance:

Polycarbonate (PC) : with excellent weather resistance and UV resistance, it is widely used in outdoor optical and electronic 

equipment fields.

Polyethylene (PE) : has good weather resistance, especially high-density polyethylene (HDPE) weather resistance is better, often 

used in storage tanks, water pipes and other fields.

Polypropylene (PP) : It has certain weather resistance and ultraviolet resistance, and is often used in automotive parts, outdoor furniture and other fields.

Polystyrene (PS) : has good weather resistance, often used in outdoor billboards, decorative materials and other fields.

Polyester (PET) : good weather resistance and UV resistance, often used in food packaging, fiber and other fields.

Polyvinyl chloride (PVC) : It has certain weather resistance and ultraviolet resistance, and is often used in construction materials, 

wire and cable and other fields.

Polyamide (PA) : It has good weather resistance and certain ultraviolet resistance, and is often used in the field of automotive parts and engineering plastics.

Polyformaldehyde (POM) : good weather resistance and UV resistance, often used in precision mechanical parts, electronic parts and other fields.

Polytetrafluoroethylene (PTFE) : has excellent weather resistance and ultraviolet resistance, often used in chemical pipelines, valves and other fields.

Polyvinyl alcohol (PVA) : It has good weather resistance and certain anti-ultraviolet ability, and is often used in food packaging, 

textiles and other fields.

It should be noted that different application areas have different requirements for plastics, and the plastics listed above are only the types with better weather resistance and UV resistance in general, and the specific selection should be carried out according to specific needs.
