Rigid PVC Compound, also known as uPVC (unplasticized polyvinyl chloride), is a thermoplastic material formulated with litter or no plasticizers. This makes it hard, durable, and dimensionally stable, ideal for products that must maintain shape and strength under mechanical or environmental stress. With its excellent balance of performance and cost, it is one of the most widely used materials in construction and industrial manufacturing.

Composition and Key Properties

Rigid PVC compound is produced by blending PVC resin with carefully selected additives such as stabilizers, lubricants, impact modifiers, and pigments. Each component plays a vital role in ensuring smooth processing and consistent product quality.

Key properties include:

• High tensile and impact strength
• Excellent resistance to chemicals and corrosion
• Dimensional stability under temperature changes
• UV and weather resistance
• Good electrical insulation
• Flame retardant and recyclable

These features make it a sustainable and cost-effective alternative to metals and other materials in many applications.

Main Applications 

1. Pipes

Rigid PVC compound is the preferred material for water supply, drainage, irrigation, and conduit pipes. PVC pipes are lightweight, corrosion-free, and resistant to chemical attack. They offer smooth internal surfaces for high flow efficiency and long-term durability, even under harsh outdoor or underground conditions.

2. Fittings

PVC fittings, such as elbows, tees, and couplings,are made from rigid PVC compound using injection molding. These parts provide tight sealing, high mechanical strength, and precise dimensions. Their rigidity ensures reliable connection and long-lasting performance in both pressure and non-pressure systems.

3. Profiles

Rigid PVC compound is extensively used for window and door profiles, wall panels, and ceiling boards. Profiles produced from high-quality compounds are UV-stabilized and impact-resistant, maintaining color, gloss, and shape even when exposed to sunlight and weathering.

4. Sheets

Rigid PVC compound is also used to extrude sheets and panels for furniture, construction, advertising, and industrial purposes. PVC sheets are smooth, easy to cut, and can be printed, laminated, or thermoformed. Their combination of strength, light weight, and workability makes them highly versatile.
