产品描述
Compound PP is EPR modified material designed for automobile bumper facia. It features high-impact strength and weatherproof stability\when used on automobile bumper facia.
In addition, these grades exhibit appropriate anti-heat levels, resistance to strain, and excellent processability. When formed, they also feature an improved external finish, superior size stability and peel resistance.
Description
Compound PP designed for the car bumper facia provides high impact- resistance, superior processability, peeling resistance, weatherability, and the following:
▶ Superior impact-resistance in low temperatures (for 5 mile bumpers)
▶ Excellent processability;
▶ Superior peeling resistance;
▶ Low linear expansion coefficient.
Applications
▶ High-impact (up to 5 miles per hour) car bumper fascia,
1) Impact-resistance in low temperatures,
2) Superior productivity;
3) Excellent peeling resistance.
▶ 2.5 mile painted and/or non-painted bumper fascia,
1) Maintains optimum balance of impact-resistance and rigidity;
2) Superior scratch-resistance;
3) Superior peeling resistance.
