What is uPVC

uPVC stands for Unplasticized Polyvinyl Chloride. It is a rigid, high-performance polymer material widely used for manufacturing window and door profiles. Unlike conventional PVC, uPVC does not contain plasticizers, making it stronger, more durable, and highly suitable for long-term architectural applications.

At Durakraft, uPVC is carefully formulated and precision-engineered to meet Indian climatic conditions, ensuring consistent performance, structural stability, and long service life.

How uPVC is Made

uPVC profiles are produced through a controlled extrusion process, where PVC resin is blended with selected additives and processed under regulated temperature and pressure conditions. This ensures uniform profile geometry, smooth surface finish, and consistent material behaviour. The absence of plasticizers results in a hard, stable profile structure that does not warp, rot, or corrode over time.

Key Components Used in uPVC Formulation

Durakraft uPVC profiles are manufactured using a balanced combination of:

• PVC Resin - The base polymer providing strength and rigidity
• Heat Stabilizers - Prevent thermal degradation and improve weatherability
• Impact Modifiers - Enhance toughness and resistance to impact
• UV Stabilizers & Titanium Dioxide (TiO2) - Improve UV resistance, colour retention, and surface whiteness
• Processing Aids & Lubricants - Ensure smooth extrusion and uniform melt flow
• Fillers (Low & Controlled Content) - Improve dimensional stability while maintaining strength

This controlled formulation ensures durability, colour stability, and long-term reliability.

Why uPVC is Ideal for Windows & Doors

uPVC has become the preferred material for modern fenestration systems due to its superior performance characteristics:

• Resistant to weather, moisture, and corrosion
• Does not warp, rot, or rust like wood or metal
• Termite-proof and pest-resistant
• Excellent thermal insulation for energy efficiency
• Effective sound insulation for quieter interiors
• Requires minimal maintenance

Long service life with consistent performance
