Introducing High-Density Polyethylene (HDPE)

High-density polyethylene is one of the raw materials we use, however much less than polypropylene and Acetal. As the name indicates, it is a denser version of polyethylene, and this increased density offers added characteristics desirable for some products.

These added molecules per weight give this plastic a high rigidity and excellent resistance while it retains its high versatility to be thermoformed in various shapes. It also does not absorb water, making it ideal for liquid containers, and it resists chemicals. Finally, it is a very light material that keeps large products relatively light in weight.

At Simport, we have selected it for our famous B350 series of 24-hour containers. We were the pioneers of a 90 switch in this product line by being the first to introduce a horizontal container. Providing users with a large carry handle and is much more stable and less prone to falling over. We have even designed a trapezoid shape that simplifies the collection, but we are drifting away from resin here. HDPE suits itself very well to blow molding, a manufacturing technique in which air is blown inside a tube of resin to make it adopt the shape of the mold. It lends itself to be molded in this unique shape, remains light even when filled with liquid, and will resist the chemicals used as preservatives for the urine.

The fact that HDPE is safe for use with foods and that kitchen cutting boards are often made with this resin makes it the logical choice for our version of a cutting board, the M620 series histology grossing cutting board. The rigidity and resistance of a thicker product here are ideal for the intended use, and the water resistance makes it easy to wash, clean, and disinfect, essential features to mitigate possible cross-contamination.

Only one other product is made of HDPE at Simport. Our S207 scintillation vial can be purchased in HDPE or PP material. HDPE provides a stiffer tube closer to glass in rigidity and is not as translucent as polypropylene. Whatever the application, our R&D experts will offer the right product molded with the proper raw material!
