Plasti-Block high density polyethylene HDPE plastic block is made of high quality and durable material. It is an ideal material for a wide range of applications in different industries. They are made with low internal stress and are easy to machine, saw, drill, and mill. They are also lightweight and easy to handle. Made of high-density polyethylene, each block can withstand cutting, drilling and other machining. Whether you need material for prototyping, DIY projects around the home or engineering samples, these blocks will handle whatever you throw at them.
Strength & Durability
HDPE is known for its high strength-to-density ratio, making it lightweight yet strong. It is resistant to impact, chemicals, and environmental stress cracking.
Plasti-Block Blocks
All blocks are molded using our own unique proprietary color blending and molding technologies, manufacturing high-quality blocks with minimal to no internal stresses.
Plasti-Block plastic blocks are suitable for producing high-quality parts using techniques such as fabrication, machining, heat gun shaping, bending.
Density & Structure
HDPE has a higher density compared to other polyethylene grades due to minimal branching in its polymer chains. This results in tightly packed molecules, leading to increased density and rigidity.
