Company Information

  Recycled plastic PET PBT PC chain extender additives

We provide solid acrylic resins powder,PMMA/PS microspheres and silicone resin powder includes BMA/MMA, EA/MMA,EMA/MMA, MMA, BMA, IBMA, Styrene and so on various copolymer of acrylate series widely used in coatings, inks ,plastic, LED cover, LCD diffusion film and cosmetic. 

Product Description


                                                                       Product Code:PCE901

PET and PBT resins Chain Extender


PCE901 is a low-cost additive converting recycled PET flakes into high-IV crystalline pellets that can be used in high-value applications ( bottles, strapping, foam, engineering alloys/compounds ).



A dramatic improvement in the performance of PCE901 if it is added to the extruder in a concentrate using a polyarbonate (PC) carrier.


Suggested Uses:

Enhancement of the intrinsic viscosity of PET and PBT -Reactive extrusion of PET and PBT -Melt strength enhancement of PET and PBT for the production of blown foams -As a melt viscosity and melt-strength-enhancing additive for modifying PET for film blowing and extrusion blow moulding applications -Upgrading of recycled PET flake to resin suitable for bottling applications(>0.80 dL/g) -As an additive to reduce the time necessary for solid-phase polymerization of PET and PBT resins -To increase the elongational viscosity of PET and PBT resins by facilitating extended and branched architectures



Silicone Microsphere (INCI name : Polymethylsilsesquioxane)

LED PC cover Silicone resin powder for light diffusion agent


Silicone mono-dispersion microspheres provide ultra-uniform and higher transparency than inorganic micro-powder. It can be wildy used in PMMA, PC, PS, PVC and PET masterbatches and increase light diffusion and luminance


  • Ø   Narrow particle size distribution
  • Ø   Matting agent
  • Ø   Anti-blocking agent
  • Ø   Excellent transparency, light diffuse effect and luminance
  • Ø   Very high heat resistance over 350 degree

Typical propeties

l   Physical form                    white micro powder

l   N.V.                                     > 98%

Product Code:ACL4                                  

PC/PS/MS plate as light diffusion agent PMMA Spherical Micro beads
 (INCI Name : Cross-linked polymethyl methacrylate)


PMMA microsphere is an easy to disperse in solvent, waterborne and UV-curable coatings that it also can act as a matting agent, widely used as a texture surface for UV inks, Coil coating, Home appliances, Wood coating, Leather finishing and Plastic film or Glass anti-blocking agent.


  • Ø   Anti-scratch, Anti-blocking and Matting agent.  
  • Ø   Texture paint.
  • Ø   Particle size can be controlled within the range of 3~120um.
  • Ø   Solvent resistance(Non-swelling in MEK and BA related solvents).
  • Ø   PMMA’s composition can be modified such as softness, heat-resistance and refractive index.
  • Ø   Processes for applying coating by brush, roller and spray.
