Methyl Tin Mercaptide
Methyl tin mercaptide is the workhorse heat stabiliser for rigid PVC, giving high early colour hold and outstanding clarity at low addition levels. Supplied as a clear liquid in grades tuned for rigid extrusion and for calendered and blown film.
Methyl Tin Mercaptide for CPVC
A methyl tin mercaptide formulated for chlorinated PVC, where the higher chlorine content and processing temperature defeat stabilisers designed for ordinary PVC. Supplied as a clear liquid and as a 25 kg powder.
Methyltin Maleate
A solid methyltin maleate heat stabiliser made from maleic anhydride and methyltin oxide, used where rigid transparency and condensation catalysis are wanted. White powder; classified as toxic and water-insoluble.
Methyltin Oleate
A methyltin heat stabiliser built on vegetable-oil derived oleic acid rather than a mercaptoester, giving a sulphur-free, odourless product with good lubricity and outdoor weather endurance.
Methyltin Organic Acid
A tin-carboxylate catalyst rather than a heat stabiliser: used as a curing and drying catalyst for polyurethane, polyester and silicone systems. Clear liquid.
Monobutyltin Oxide (MBTO)
Monobutyltin oxide (CAS 2273-43-0) is an esterification catalyst for saturated and unsaturated polyester resins, used in powder coatings, coil coatings and insulating paints. White powder.
Monobutyltin Trichloride
Monobutyltin trichloride (CAS 1118-46-3) is used to produce butyltin stabilisers and, significantly, as the tin precursor for the hot-end coating applied to glass containers. Light amber clear liquid.
PVC External Lubricant
External lubricants control how PVC melt releases from hot metal, preventing plate-out and die build-up. Supplied as powders and flakes across grades for pipe, profile, foam board and master batch.
PVC Internal Lubricant
Internal lubricants reduce friction between polymer chains themselves, lowering melt viscosity and frictional heat without delaying fusion. Grades for transparent sheet, film, pipe and CPVC.
PVC Internal and External Lubricant
Dual-action lubricants that provide both internal viscosity control and external release from a single addition, used in cable compounds, TPE process aids and wax emulsions.
PVC Lubricant Wax Powder
Fine wax powders dispersible directly into solvent-based coatings and inks at 0.5-3%, and a granular grade for rigid PVC extrusion and injection moulding.
Phosphite Antioxidant 168
A secondary antioxidant that destroys hydroperoxides before they can split into new radicals, used alongside hindered phenols rather than instead of them.
Polyester Wax Dispersant
A polyester wax with a distinctive molecular structure that lubricates internally and externally while wetting and dispersing pigment, used in engineering plastics and masterbatch.
Polyvinyl Chloride Paste Resin
Emulsion and microsuspension PVC resin that disperses in plasticiser to form a plastisol rather than melting, used for coating, dipping and rotational moulding. Supplied across grades from many Chinese producers.
Polyvinyl Chloride Resin (Suspension Grade)
Suspension PVC resin (CAS 9002-86-2) graded SG1 to SG8 by K value, sourced from major Chinese producers. SG5 is the general-purpose grade for pipe and profile.
Potassium Zinc Heat Stabiliser
A liquid potassium-zinc stabiliser developed for PVC wallpaper foam, where the stabiliser must not interfere with the chemical blowing system.
Reverse Ester Methyltin
A reverse-ester methyltin stabiliser for pressure and impact-modified PVC pipe, where regulatory acceptability in drinking-water contact matters as much as thermal performance. Light yellow to clear oily liquid.
Stannous Octoate (Tin Catalyst T-9)
Stannous octoate (CAS 301-10-0) is the standard tin(II) gelling catalyst for flexible polyurethane slabstock foam, and is also used in RTV silicone cure. Light yellow liquid.
Tetrabutyl Tin (TBT)
Tetrabutyltin (CAS 1461-25-2) is the fully alkylated starting material for the butyltin series and a direct catalyst for olefin polymerisation. Transparent liquid.
UV Absorbers and Light Stabilisers
Two distinct chemistries for outdoor durability: UV absorbers that convert ultraviolet energy to heat before it breaks bonds, and hindered amine light stabilisers that interrupt the photo-oxidation cycle itself.
