LDV-8010
VOC Removal Masterbatch. Removes unwanted organics and VOC emissions at compounding time instead of masking them.
ST-PETS
Premium Pentaerythritol Tetrastearate Mold Release. Provides exceptional mold release for complex geometries without compromising transparency in PC or causing plate-out in nylon.
ST-SR487
Halogen-free flame retardant for thin Polycarbonate films
ST-HT11 & ST-HT312
Heat Stabilizers. Essential capabilities such as anti-yellowing and protecting polymers against heat aging. Prolongs lifetime of polymers.

Endothermic Closed-Cell Foaming Agent Masterbatch. Reduces part weight by 10%+ while maintaining structural integrity and uniform cell size.
ST-FR6
High-Efficiency Flame Retardant Synergist for PVC. Replaces standard ATO directly in PVC formulas to provide significant cost savings and protect your margins from ATO price spikes.
ST-4210
Low-VOC ABS Compatibilizer. Substantially improves the phase morphology and mechanical robustness (impact strength, elongation) of PA/ABS and PC/ABS alloys.
ST-PA229C
PET/PBT flow improver
ST-T78MB
Transesterification Inhibitor. Solve issues with polyester alloys such as discoloration, brittleness, or foaming caused by transesterification. Maintain Heat Distortion Temperature and avoid loss of molecular weight in copolymers.
ST-AN3220
Low-VOC PA/ABS Compatibilizer. A highly functionalized, low emission compatibilizer that physically locks the PA and ABS phases together at the molecular boundary.
