PRODUCT INTRODUCTION
Our Toughening Modifier is a high-performance polymer impact additive developed to raise fracture toughness, impact strength and ductility of rigid matrix materials, without severely sacrificing tensile strength, heat resistance or processing flowability. It works by forming flexible micro-phase domains inside the base material, absorbing impact energy and stopping crack propagation when external force or low-temperature shock occurs.
This Toughening Modifier covers two major application tracks: engineering plastic compounding and dry-mix construction materials. For plastics, it improves low-temperature impact resistance for PP, PA, PC/ABS, PBT, PVC and filled reinforced systems. For mortar, grout and waterproof coatings, it increases flexibility, anti-crack performance and deformation tolerance under thermal cycling and substrate movement.
The product series includes powder and pellet grades with different grafting degrees and compatibility. It shows good interfacial bonding with most polymers, cement binders, cellulose ethers, RDP and mineral fillers. When dosed properly, it reduces brittleness, lowers cracking risk and stabilizes long-term mechanical performance.
Every batch of Toughening Modifier is inspected for melt index, particle size, impact boosting efficiency and dispersion stability before shipment. Full export documents including COA, TDS and SDS(MSDS) are provided for customs clearance and quality traceability. Our technical team can match the best grade and dosage according to your base material, working temperature and target mechanical indicators, as well as destination country compliance rules.

USAGE NOTES
Dosage Control:
The recommended dosage of the Toughening Modifier is 1–8% based on different systems. Excessive addition may reduce rigidity, heat distortion temperature or surface hardness. Start low and raise dosage after mechanical testing.

Adding Method:
For plastic extrusion/compounding: feed together with resin and filler at twin-screw. For dry mortar: mix uniformly with all dry powder components before water addition.

Compatibility Check:
Before mass production, test the Toughening Modifier with antioxidants, stabilizers, pigments, cellulose ethers and RDP. Observe dispersion, surface quality and mechanical retention. For EU export, REACH SVHC screening is suggested.

Process Condition Consideration:
For plastic systems, adjust extrusion temperature and shear strength to guarantee uniform dispersion. For mortar, avoid over-mixing which may damage polymer structure.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Still Brittle, No Improvement of Impact Strength
Poor compatibility, insufficient dosage or wrong grade leads to no obvious toughening effect.
Solution: Switch to grafted reactive grade, increase dosage properly and check dispersion uniformity in compounding.
Rigidity & Heat Distortion Temperature Drop Too Much
Overdosing of flexible Toughening Modifier sacrifices hardness, modulus and heat resistance.
Solution: Reduce dosage, select high-efficiency grafted grade instead of simple elastomer, balance toughness and rigidity.
Poor Dispersion, Visible White Spots & Fish Eyes
Insufficient shear, bad feeding sequence or agglomerated modifier pellets/powder.
Solution: Optimize screw speed and temperature curve, pre-blend powder materials, check raw material moisture.
Mortar Crack Resistance Not Improved
The plastic-type toughener cannot form effective flexible network inside cement matrix.
Solution: Use TM-400 mortar dedicated Toughening Modifier and cooperate with RDP together.
Surface Gloss Reduction, Matte & Rough Surface
Excessive modifier or poor interfacial compatibility destroys surface smoothness of plastic parts.
Solution: Adjust dosage, use low-addition high-efficiency grade, optimize mold temperature.
Long-term Aging Toughness Decay Fast
The Toughening Modifier lacks anti-oxidation protection and degrades during outdoor service.
Solution: Match with suitable antioxidant and light stabilizer in the formula.
Customs Detention Due to Mismatched Documents
Incorrect HS code, CAS number or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, CAS No.26221-73-8 (reference), non-hazardous. We supply consistent full-set SDS / COA documents.
Batch-to-Batch Mechanical Performance Drift
Variation of raw material melt index, moisture and mixing parameters causes unstable impact value.
Solution: Fix Toughening Modifier grade and dosage, control raw material moisture, test impact strength for each incoming batch.
