Exxelor VA 1803 (CAS:ExxonMobil)

Product Description

Exxelor VA 1803 polymer resin is a high flow, amorphous ethylene copolymer functioinalized with maleic anhydride by reactive extrusion. Its fully saturated backbone results in outstanding thermal and oxidative stability leading to enhancd weatherabilit. Moreover, its amorphous nature exhibits impact resistance at very low temperatures in blends with engineering polymers such as polyamide.

This grade is designed to:

1. Modify the impact characteristcs of the full range of polyamides for temperatures as low as-40°C(a function of the modifier treat level in the blend).

2. Offer the best balance between stiffness and low temperature performance in polyamide blends.

3. Modify the impact characteristics of other engineering thermoplastics and technicalpolymers(with or without glass fibers, fillers, etc.)

4. Achieve compatibility between polyolefins and more polar polymers that are capable of interacting with maleic anhydride.

Key Features

Performance enhancements in polyamide blends:

 Outstanding notched lozd impact resistance at room temperature

Consistent and very high notched lzod impact resistance down to -40°C

Improved flexibility.

Reduced moisture sensitivity and improved dimensional stability allowing the production of molded parts with different wall thickness.

Improved assembly of freshly molded parts.

Increased impact resistance of glass-reinforced compositions.

Processing Statement

Exxelor VA 1803 resin can be added to polyamide to achieve optimum dispersion within the polymer matrix(average particle size below 1 micrion) in order to obtain the best performance. Its low viscosity makes it particularly suitable for processing glass-reinforced PA compositions. Compounding parameters that can  lead to optimizer performance including extruder type, screw design, barrel temperature, screw speed, throughput and residence time. Our experienced technical service engineers and chemists are always on hand to help you in achieving the best performance from your processing and compunding operations.
