Product Introduction: Toughened Mineral-Filled PP (PP+EPDM-T20)
Color Code: YS269 Light Grey
1. Product Overview
PP+EPDM-T20 (YS269) is a high-performance Polypropylene (PP) composite material modified with Ethylene Propylene Diene Monomer (EPDM) rubber for toughening and filled with 20% fine talc (T20).
Specifically pre-colored to the automotive industry standard YS269 Light Grey, this material is engineered to balance structural rigidity with superior impact resistance. It is widely used for interior trim and visible exterior components where color consistency, low odor, and high surface quality are critical.
2. Key Features
Balanced Mechanical Performance: The 20% talc content provides excellent dimensional stability and stiffness, while the EPDM rubber ensures the material remains tough and ductile even at low temperatures (preventing brittle shattering).
Precise YS269 Color Matching: Utilizing advanced pre-coloring technology, this grade guarantees consistent "Masterbatch-free" color across batches, reducing painting costs and offering excellent UV resistance against yellowing.
Low VOC & Low Odor: Formulated to meet strict automotive environmental standards (such as VDA 270), minimizing the emission of volatile organic compounds (VOCs) to ensure superior cabin air quality.
Low Shrinkage & Anti-Warping: The mineral filler significantly reduces the natural shrinkage of PP, allowing for high precision in large-scale molded parts with minimal deformation.
Premium Surface Finish: Designed with optimized flow characteristics to prevent common surface defects such as tiger stripes, flow marks, or sink marks.

4. Application Fields
I. Automotive Interior Systems
Typical Components: Dashboard lower panels, glove box assemblies, center console side trims, door panels, and pillar garnishes (A/B/C pillars).
Benefit: The YS269 Light Grey provides a clean, premium aesthetic that integrates seamlessly with modern cabin designs.
II. Automotive Exterior Components
Typical Components: Wheel arch liners, mudguards, and protective side moldings.
Benefit: EPDM toughening ensures the parts do not crack or break when struck by road debris or stones.
III. Precision Appliances & Industrial Housing
Typical Components: Washing machine top covers, vacuum cleaner housings, and control panels for industrial equipment.
Benefit: Offers a clean industrial look with high durability and resistance to environmental stress.
5. Processing Guidelines
Drying: While PP has low moisture absorption, it is recommended to dry the material at 80°C for 2 hours to ensure a flawless surface finish and color stability.
Melt Temperature: 200°C - 230°C.
Mold Temperature: 40°C - 60°C. Proper mold temperature is essential for optimizing surface gloss and texture replication.
Injection Speed: Moderate speeds are recommended to avoid localized discoloration or gas entrapment caused by high-shear friction.
