Advantages of HDPE Plastic in Injection Molding
Also known as polyethylene high-density (PEHD), HDPE is a polyethylene thermoplastic made from petroleum. Its high strength-to-density composition and versatility make HDPE a very popular type of plastic, serving a wide array of industries. From food storage containers to piping systems, HDPE does it all.
Benefits of HDPE include:
- Weather-resistance
- Malleability
- Light-weight
- Cost-effective
- Hygienic
- Recyclable
- FDA-approved
High-Density Polyethylene can be molded into a variety of different shapes and sizes. With its linear structure and optimal strength, HDPE can withstand environmental stresses such as high-temperature treatment and physical impact.
