Polypropylene (PP) is a leading thermoplastic, known for its rigid yet adaptable nature, making it perfect for everyday items like packaging trays, battery cases, medical devices, and more. Part of the polyolefin family, it’s among the top three most-used polymers worldwide. PP’s ultra-low density means it’s incredibly lightweight without sacrificing strength.
Polyethylene (PE) is a versatile, lightweight, and durable thermoplastic—widely produced for countless industries. At GB Plas, we offer both High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE). Each has distinct properties to meet your unique requirements, whether you need strength or flexibility. Here’s a quick guide:
Among commodity plastics, PP is lightweight yet tough, ideal for a range of applications.
Suitable for packaging, automotive parts, and textiles.
Resists chemicals and bending, making it perfect for hinges, lids, and high-use items.
Ideal for electrical goods or products exposed to moisture.
Smooth surface, great for moving parts in machinery.
Strong, lightweight, and affordable.
HDPE is your go-to choice for applications requiring strength, rigidity, and heat resistance. It’s highly durable with a high tensile strength, making it perfect for heavy-duty products that need to withstand demanding conditions. HDPE is opaque, offering strong UV protection and superior resistance to acids, bases, oils, and solvents.
LDPE offers excellent flexibility even at low temperatures, making it ideal for products needing durability without compromising flexibility. LDPE's semi-transparency and impact resistance allow it to absorb shocks, making it great for protective films, bags, and flexible pipes. It’s a lightweight, affordable solution that doesn’t compromise on quality.
