Moisture-Resistant Plastic Pellets
These pellets resist swelling when exposed to water, making them suitable for use in wet environments. Melt and mold them into desired shapes. Pellets are made from virgin resins and are compatible with various types of molding equipment such as injection molders and 3D printers.
Choose HDPE pellets for general-purpose applications such as protoyping.
