Hangzhou Meilin New Material Technology Co., Ltd. is China ODM/OEM Matte Data Cable Compound Suppliers and Wholesale Matte Data Cable Compound, we were established in July 1994 (formerly known as Zhejiang Lin'an Hongyan Plastic Factory). The company has two factories located at 619 Linglongshan Road and 259 Xingyu Street, Lingqiu Street, Linglong Industrial Park, Lin'an District, Hangzhou City. The registered capital of the company is 75 million yuan, covering an area of over 18000 square meters and a building area of over 30000 square meters. Currently, modern industrial factories and 18 advanced automated production lines have been built. The new factory area will be produced in 2021, making it the cleanest and most beautiful professional cable material manufacturer in the entire region—agreement conditions.
A Medical Polyvinyl Chloride Compound is not defined by its base resin alone — flexibility, transparency, chemical resistance, and processing behavior all come from the combination of resin grade, pl...
A 90 °C halogen-free sheathing compound can pass the single-wire EN 60332-1-2 flame test and still fail the Cca classification written into the purchase order. EN 50399 measures heat release on a tr...
When a 132 kV cable fails its routine partial-discharge screen at 5 pC, the extrusion line is examined first and the compound is examined last. The order is usually reversed. Partial discharge, hot-...
Three hours into the first run of a low-smoke halogen-free sheath compound, the operator at a cable plant in Hangzhou watched the extruded surface turn chalky, a white ring form on the die face, and ...
Matte Data Cable Compound is popular in consumer electronics, smart devices and other fields due to its delicate touch, wear resistance, scratch resistance and high-end appearance. However, its performance requirements are far more than appearance, and it must also meet multiple technical standards such as electrical performance, mechanical strength, and environmental compliance.
Appearance and touch
Matte effect: It needs to be uniform and spot-free to avoid the "plastic feel" of traditional PVC or TPU.
Anti-fingerprint/anti-fouling: Surface treatment technology (such as adding special additives) reduces grease adhesion.
Mechanical properties
Abrasion resistance (ASTM D4060): No cracks after repeated bending (such as more than 100,000 times).
Flexibility (ISO 6722): It remains soft at low temperatures (-20℃ to -40℃) to avoid embrittlement.
Tensile strength (ISO 37): It is usually required to be ≥10MPa to ensure the durability of the cable.
Electrical properties
Dielectric constant and loss (IEC 60250): Affects high-speed data transmission (such as USB4/Thunderbolt 4).
Shielding effectiveness (EN 50396): Conductive fillers (such as carbon black) in composite materials need to balance matte and EMI shielding requirements.
Environmental adaptability
UV aging resistance (ISO 4892): Outdoor use must pass QUV test for more than 500 hours.
Flame retardant grade (UL 94/IEC 60332): At least VW-1 or HF1 level, meeting consumer electronics safety standards.
Environmental compliance
Halogen-free requirements (IEC 61249-2): Bromine/chlorine content <900ppm (such as EU RoHS, REACH).
Recyclability: Bio-based TPU or PP materials are gradually becoming a trend.
