Our advantages

  • Performance advantage

    Improved hand-folding, compression performance, and good gloss

    Polyester homopolymer replaces CPE, offering better toughness and meeting the standard for 5-degree hand folding

    Improve pressure resistance to meet national standards

    High-speed extrusion, smooth surface, and excellent gloss

  • Cost advantage

    Reduces both formula and overall costs

    Increase production capacity and optimize extrusion speed. From 12-14 m/min to 16-20 m/min

    Heavy calcium can be used without compromising performance and gloss, optimizing cost

    Reduces precipitation and greatly prolongs startup time

    Improved yield

  • Production advantage

    Precipitation reduction

    Extend start-up time

    Continuous stability

    Multi-machine adaptation

Frequently Asked Questions

  • How do you keep output stable at speed and cut plateout?

    +

    Go with a polyester wax + polyester homopolymer combo tuned for molecular weight and low volatility. Dial in internal/external ratios and reduce the total lube. You’ll stretch run time and clean less, across multiple machines.

  • Struggling with the 5°C cold bend?

    +

    Swap CPE for polyester homopolymer to build those fine “energy-absorbing” phases. Combine with the right lubrication and toughening, and you’ll pass the 5°C hand-bend while keeping surface and dimensions steady.

  • Heavy CaCO3 dragging gloss and toughness down?

    +

    · Choose the right particle size and surface treatment.

    · Use polar polyester wax to improve dispersion.

    · Add polyester homopolymer to get toughness back.

    Result: cost down, glossy finish, no fuzz, and solid mechanics.
