Acrylic Impact Modifier
All-acrylic core-shell modifiers for outdoor rigid PVC, chosen over MBS where long-term weather resistance matters more than transparency.
Acrylic Processing Aid (ACR)
High molecular weight acrylic polymers that promote fusion and melt strength in rigid PVC, improving surface quality without acting as lubricants.
Barium Cadmium Zinc Heat Stabiliser
A liquid barium-cadmium-zinc stabiliser for transparent PVC. Cadmium content restricts its use in many markets and it should only be specified where cadmium is permitted for the intended article.
Barium Zinc Heat Stabiliser
Cadmium-free barium-zinc stabilisers for flexible PVC: the liquid grade for soft film and leather, the powder grade for foamed shoe materials and leathers.
Butyl Tin Mercaptide
A butyltin mercaptide heat stabiliser for high-transparency PVC sheet, film, pipe and profile. Transparent liquid supplied in IBC tote or drum.
Calcium Zinc Compound Stabiliser
The non-toxic replacement for lead stabilisers in PVC, supplied as a graded series covering medical and food-contact soft PVC, wire and cable, pipe, injection fittings, profile, foam and transparent product.
Chlorinated Polyethylene (CPE 135A)
CPE 135A (CAS 63231-66-3) is the general-purpose impact modifier for rigid PVC, valued for low-temperature toughness and its tolerance of high filler loadings.
Compound Calcium Zinc Tin Stabiliser System
A one-pack white granular stabiliser combining calcium and zinc soaps with an organotin component, aimed at pipe applications that want tin performance without a fully tin-based cost base.
Di(2-propylheptyl) Phthalate (DPHP)
DPHP (CAS 53306-54-0) is a high molecular weight phthalate used where low volatility and good electrical properties matter, and which falls outside the classification applied to the low molecular weight phthalates.
Dibutyltin Dichloride
Dibutyltin dichloride (CAS 683-18-1) is the intermediate for butyltin stabilisers and catalysts, and a reactive additive that improves carbon black dispersion in synthetic rubber. White needle-shaped crystal.
Dibutyltin Dilaurate (DBTDL)
Dibutyltin dilaurate (CAS 77-58-7) is the reference catalyst for polyurethane foam and RTV silicone cure, and doubles as a PVC stabiliser and lubricant. Light yellow transparent liquid.
Dibutyltin Maleate
A sulphur-free butyltin heat stabiliser in white amorphous powder form, used for rigid clear PVC, ABS engineering plastics and as a condensation catalyst.
Dibutyltin Oxide (DBTO)
Dibutyltin oxide (CAS 818-08-6) is the white powder intermediate for dibutyltin laurate, maleate and monobutyl maleate, and is used in self-polishing marine antifouling coatings.
Dimethyltin Dichloride (DMTC)
Dimethyltin dichloride (CAS 753-73-1) is the feedstock for methyltin stabilisers and the tin source for chemical vapour deposition of tin oxide onto glass. Supplied as white crystalline solid or as an aqueous solution.
Dimethyltin Oxide (DMTO)
Dimethyltin oxide (CAS 2273-45-2) is the white powder intermediate from which methyltin stabilisers are built, and a catalyst in its own right for powder coating and polyester resin.
Dioctyl Sebacate (DOS)
Dioctyl sebacate (CAS 122-62-3) is the cold-flexibility plasticiser: a sebacic-acid ester that keeps PVC pliable at temperatures where phthalates stiffen. Often used in combination with phthalates rather than alone.
Epoxidised Soybean Oil (ESBO)
Epoxidised soybean oil (CAS 8013-07-8) is a bio-based plasticiser that is also a secondary heat stabiliser, and one of the few plasticisers with broad food-contact acceptance. Light yellow sticky oily liquid.
Hindered Phenol Antioxidants
Primary antioxidants that intercept the free radicals which degrade polymers during processing and service life. Supplied as white powder or granule in the standard industry grades.
MBS Impact Modifier
Methacrylate-butadiene-styrene modifiers give rigid PVC impact resistance while preserving transparency, which is what separates them from other impact modifiers.
Methyl Tin Laurate
A white emulsion methyltin laurate positioned as a substitute for dibutyltin dilaurate in silicone and polyurethane catalysis, avoiding butyltin chemistry.
