Custom Polymer Compounding & Formulation Engineering
When commercial off-the-shelf resins fail to meet specific thermal, structural, or environmental thresholds, we engineer bespoke polymer formulations. From twin-screw trial extrusion to full-scale compounding lots, our material scientists tailor molecular rheology to match your exact application.
Engineered Across Extreme Parameters
We compound functional additives, reinforcing matrices, and stabilizers directly into base polyamides, polycarbonates, polyesters, and polyacetals.
Structural & Modulus Reinforcement
Compounding with chopped E-glass fibers, high-modulus carbon fibers, or spherical glass beads (10% to 50% loading) to drastically increase tensile modulus and limit creep under continuous mechanical load.
Halogen-Free Flame Retardancy
Environmentally compliant phosphorus-nitrogen flame retardants engineered to achieve UL94 V-0 ratings down to 0.75mm wall thickness without releasing toxic halogen gases or corroding tooling steel.
Electrical & Static Control (ESD)
Precise percolation threshold engineering utilizing conductive carbon black, carbon nanotubes (CNT), or permanent anti-static masterbatches to achieve surface resistivities from 10^3 to 10^10 ohm/sq.
Tribological & Wear Resistance
Eliminate external grease and avoid squeak-and-rattle noise. Compounding with micropowder PTFE, silicone masterbatch, and molybdenum disulfide (MoS2) for ultra-low dynamic friction coefficients.
Thermal & Weather Stabilization
Stabilizer packages formulated with primary hindered phenol antioxidants, secondary phosphites, and HALS light stabilizers to withstand continuous 150°C heat aging and severe Florida-cycle UV weathering.
Low-Warpage & Shrinkage Control
Mitigate anisotropic differential shrinkage in thin-walled housings by hybrid-compounding aspect-ratio minerals, glass beads, and impact modifiers to ensure flat, dimensionally stable large parts.
From Target TDS to Production Lots
A disciplined, empirical compounding development process designed to reduce iterations and secure mold trial success on the first attempt.
Specification Intake & Benchmark
Our polymer engineers dissect your target TDS requirements, operating temperature, regulatory compliance criteria, and mold tooling geometry (gate size, flow length).
Design of Experiments (DOE)
Formulating matrix variations adjusting virgin resin MFR, additive loading percentages, and coupling agents to achieve the optimum balance between mechanical toughness and melt flow.
Pilot Twin-Screw Extrusion
Compounding a 25kg - 50kg pilot batch on high-torque intermeshing co-rotating twin-screw extrusion lines with precise loss-in-weight gravimetric feeding controls.
Laboratory Testing & Injection Trials
Injection molding standard test specimens in-house. Comprehensive verification of tensile strength, flexural modulus, Izod impact, HDT, MFR, and burning behavior.
Commercial Lot Scaling & COA Delivery
Transfer to multi-ton automated compounding reactors with locked extrusion thermal profiles, vacuum degassing, and 100% batch-traceable Certificate of Analysis (COA).
What Information Accelerates Formulation?
To provide the most targeted formulation proposal and material pricing, having the following operational parameters ready allows our engineering team to formulate effectively:
- Base Polymer & Filler Target: Target base resin (PA6, PA66, PC/ABS, PBT, POM) and desired filler type/load (e.g., 30% GF).
- Critical Physical Thresholds: Minimum yield strength (MPa), Notched Izod impact (kJ/m²), or Heat Deflection Temp (HDT @ 1.8 MPa).
- Environmental & Regulatory Demands: UL94 flame rating requirement, chemical contact exposure (oils, fuels, disinfectants), or FDA/RoHS needs.
- Molding Constraints & Annual Volume: Wall thickness range, runner system (hot vs cold), target pilot trial volume, and forecasted annual consumption.
