Low and High Density Polyethylene Profiles and Recycled Polyethylene Plastic Profiles
Polyethylene is a fairly “old” material first developed in the 1930’s. Polyethylene is one of the lowest cost materials and has some amazing properties. Polyethylene profiles have good impact strength from temperatures as low as -40° F and up to 176° F. Polyethylene profiles are considered to be fairly “flexible” and have excellent chemical resistance along with resistance to moisture absorption. Because of Polyethylene’s excellent chemical resistance, it is almost impossible to bond with adhesives. We do however have a product that we can recommend. Polyethylene profiles are easy to process and are lightweight (floats on water). Polyethylene plastic will tolerate some outdoor exposure but is not considered a weatherable material. Polyethylene can be coextruded with some thermoplastic Elastomers (TPEs). Polyethylene will burn quite readily (similar to a candle). Polyethylene profiles have an upper service temperature of about 180° F depending on the grade.
Low Density Polyethylene
Low Density Polyethylene (LDPE) is translucent or opaque, is quite flexible and fairly tough. When colored, LDPE profiles have a glossy finish.
High Density Polyethylene
High Density Polyethylene (HDPE) has increased tensile strength, is more rigid, has better chemical resistance, and can withstand higher temperatures than LDPE. When colored, HDPE profiles have an opaque and generally a fairly glossy finish.
Polyethylene Profile Markets
Major markets for Polyethylene profiles include: food handling, household products, toys, chemical containers and pipe.
Recycled Polyethylene
Keller Products can use recycled Polyethylene in its profiles (LDPE and HDPE). Large-scale, municipally sponsored recycling programs exist for HDPE. Recycled Polyethylene (HDPE) is used to produce bottles for cleaners, drainage pipe, trash containers, benches, fencing, and lumber. Programs for recycling LDPE are becoming much more popular – some supermarkets offer recycling for plastic shopping bags. Recycled Polyethylene (LDPE) is used to produce trash and grocery bags, plastic tubing, agricultural film and lumber. |
