Description
Product Overview
PVC Rigid Compound (PVC-U) is an unplasticized, high-strength thermoplastic polymer designed for durability, cost-effectiveness, and versatility. Formulated without plasticizers, this compound offers excellent mechanical properties, chemical resistance, and weatherability, making it ideal for construction, packaging, and electrical applications. Atman Polymer’s PVC Rigid Compound is engineered to meet stringent industry standards, ensuring reliable performance in demanding environments.
Key Features
- High Tensile Strength: Achieves a tensile strength of approximately 50–52 MPa, ensuring structural integrity.
- Thermal Stability: Maintains performance up to a maximum operating temperature of ~60°C, with a heat deflection temperature (HDT) of ~65–70°C at 1.8 MPa.
- Chemical Resistance: Resists most acids, alkalis, and salts, suitable for harsh environments, though less resistant to strong oxidizing agents.
- Weatherability: Enhanced UV stabilizers ensure long-term durability for outdoor applications.
- Electrical Insulation: Low electrical conductivity makes it ideal for wire and cable insulation and electrical components.
Applications
- Construction: Pipes, fittings, window and door profiles, and roofing membranes due to durability and weather resistance.
- Packaging: Bottles, blister packs, and non-food containers for strength and transparency.
- Electrical: Cable ducts, conduits, and insulation for electrical components.
- Consumer Goods: Bank cards, signage, and other rigid products requiring impact resistance.
