Product Overview
E-PVC refers to a specialized resin-based polymer compound widely used in industrial applications due to its excellent adhesion, mechanical strength, chemical resistance, and electrical insulation properties.
E-PVC formulations typically consist of polymer resins combined with thickeners and functional additives, allowing manufacturers to tailor the material for different industrial uses. The exact composition may vary depending on the application, but commonly used base resins include epoxy resins and polyester resins.
Because of its high viscosity, strong bonding capability, and good thermal stability, E-PVC is widely used in industries such as automotive manufacturing, electronics, construction materials, coatings, and composite materials.
Chemical Structure
E-PVC systems generally contain polymer resins combined with stabilizers, fillers, and thickening agents to achieve the desired physical and processing characteristics.
Common resin bases include:
- Epoxy resins
- Polyester resins
The specific formulation depends on the required performance characteristics such as mechanical strength, chemical resistance, or processing behavior.
Physical Properties
Appearance
Typically a transparent or translucent paste, although color can vary depending on added pigments, fillers, or additives.
Viscosity
E-PVC formulations usually have high viscosity, which makes them suitable for coating, molding, and adhesive applications.
Density
The typical density ranges between 1.0 – 1.5 g/cm³, depending on the formulation and additives used.
Thermal Properties
Glass Transition / Melting Temperature
Different resin systems have varying thermal properties, generally within a range of 60°C – 200°C.
