Features & Benefits

Superior Weather Resistance

Tairilac WE8303 resin withstands prolonged UV exposure and extreme temperatures without cracking or fading, ideal for outdoor products like signage and roofing.

High Impact StrengthRobu

With a Charpy Impact Strength of 34 kJ/m², this resin resists mechanical stress, reducing breakage in automotive components and protective housings.

Thermal Stability

A Vicat Softening Point of 93°C ensures dimensional stability in high-heat environments, perfect for electrical enclosures and automotive under-the-hood parts.

Application

Outdoor Products:

Solar panel frames, garden equipment, and signage due to UV and moisture resistance.

Junction Boxes:

It can protect electrical components with flame-retardant (HB) and insulating properties.

Auto Parts:

Exterior trims, mirror housings, and grilles benefiting from impact resistance and color retention.
