Additives
Processing Additives Supplier
Engineered for Smoother, Stronger, Longer-Lasting Polymers
Processing additives are the unseen workhorses of modern plastics manufacturing. From the moment raw resin enters the extruder to the day the final part leaves service, these specialized chemistries protect polymer chains, optimize melt flow, and unlock the mechanical performance your applications demand. As a processing additives supplier, Sychem curates processing additive solutions that bridge the gap between resin selection and finished-product reliability — so your formulation performs the way the data sheet promised.
Why Processing Additives Matter
Three universal challenges every polymer compounder must solve
Stop Polymer Breakdown
Heat, oxygen, and UV exposure trigger chain scission and discoloration. The right stabilizer system protects your polymer through processing, storage, and decades of end-use service.
Faster Cycles, Better Clarity
Controlling how a semi-crystalline polymer solidifies directly determines part stiffness, transparency, and molding throughput — the difference between a competitive product and a commodity one.
Smoother Melts, Cleaner Parts
Reducing internal friction and mold adhesion lowers torque, prevents melt fracture, and keeps your line running. Small dosages, measurable savings on energy and scrap rates.

SYCHEM TECH is a processing additives supplier based in Shenyang, China, offering a complete processing-additive toolbox for polyolefins, engineering plastics, and elastomers — antioxidants and HALS for thermal-oxidative and UV protection, nucleating agents and clarifiers for stiffness and clarity, and internal and external lubricants for melt flow and mold release. As your formulation development partner, we match the right additive package and dosage to your resin and process, and back every grade with a TDS, COA, and REACH/RoHS support. For background, see the overview of polymer stabilizers and additives.
Looking for a reliable processing additives supplier with formulation support? Tell us your polymer, processing method, and end-use targets, and our team will recommend grades and arrange samples. Explore our antioxidants & HALS, nucleating agents, and lubricants, or browse the full functional additives range.
Most compounds use a small additive package rather than a single product: an antioxidant blend (primary phenolic plus secondary phosphite) for melt and long-term heat stability, a nucleating agent or clarifier to tune stiffness and transparency, and an internal or external lubricant to control viscosity, torque, and mold release. Typical dosages range from a few hundred ppm for clarifiers to 0.5–2% for lubricants. Tell us your resin, target properties, and processing temperature, and we will propose a starting formulation and a shortlist of grades worth sampling.
