Product Name

High-Density Polyethylene

Category

Food Grade Plastic

Description

HDPE is a type of polyethylene, the most common plastic which accounts for over 34% of the global plastic market. It is a polymer made up of a huge number of repeating units (known as monomers). The branching in high-density polyethylene is of a relatively low degree (when compared to other categories of polyethylene).

Melting Point

130.8 °C.

Density

940 kg/m³

Application

Bottle caps and bottles are made of this polymer.
It is also used in 3-D printing filaments
HDPE is used in the fuel tanks of several types of automobiles.
The piping system responsible for the distribution of natural gas is generally made of this polymer due to its resistance to corrosion and other attributes.
It is used in plastic lumber and wood plastic composites.
Skeletal and facial reconstruction surgeries (part of plastic surgery) involve the use of HDPE

Chemical Formula

(C2H4)n

Crystallinity

0.6

Feature

HDPE has a high strength-to-density ratio, meaning it is strong and lightweight. Additionally, it demonstrates resistance to mildew, mold, rot, and insects, as well as to corrosion, cracking, and weathering.
