MARK series organotin heat stabilizers

MARK organotin heat stabilizers including methyltin, butyltin and octyltin mercaptides prevent thermal degradation during PVC processing. They provide exceptional early color retention, transparency and long-term stability for rigid profiles, pipes and packaging materials.

  • Industry standard grades including MARK 1900, MARK 1984 and MARK 17 MOK lines
  • High efficiency thermal stabilization preventing dehydrochlorination in melt
  • Widely used in exterior window profiles, vinyl siding, rigid pipes and sheets
  • Select formulations meet FDA regulations for food contact containers and films

MARK series mixed metal heat stabilizers

MARK mixed metal heat stabilizers comprise liquid, paste and solid systems based on calcium-zinc, barium-zinc and organic-based chemistry. They are engineered for flexible and rigid PVC, delivering outstanding dynamic processing stability and clean surface finish on lines.

  • Environmentally sound Calcium-Zinc and heavy-metal-free organic based formulas
  • Liquid and solid grades for flexible PVC wire insulation, films and sheet goods
  • Prevention of plate-out and sticking on calender rolls and extrusion tooling
  • Uniform dispersion in plastisols, flooring coatings and synthetic leather lines

DRAPEX series epoxidized plasticizers

DRAPEX epoxidized soybean oil (ESBO) and linseed oil (ELO) plasticizers act as secondary plasticizers and co-stabilizers in PVC. Derived from renewable feedstocks, they scavenge hydrogen chloride, boost light stability and function as internal processing lubricants.

  • High purity grades including DRAPEX 39, DRAPEX 392, DRAPEX 6.8 and DRAPEX 4.4
  • High oxirane oxygen content providing efficient hydrogen chloride scavenging
  • Synergistic performance boost when combined with metal stabilizer systems
  • Approved for food packaging, medical fluid containers and children products

BLENDEX series polymer modifiers

BLENDEX polymer modifiers upgrade mechanical strength and melt processing properties in PVC, ABS, PC and polyester resins. The portfolio includes impact modifiers, AMSAN heat distortion improvers, acrylic processing aids and anti-drip agents for flame retardant formulations.

  • Impact modifiers BLENDEX 338, 3160 and SS 308 delivering low temperature toughness
  • Heat modifiers BLENDEX 5470 and 587S increasing HDT and Vicat softening points
  • Acrylic process aids BLENDEX SA 100 and SA 153 improving melt strength in foam
  • Specialty anti-drip compound BLENDEX 6530 and gloss-reducing additive BLENDEX BMAT

Liquid phosphite stabilizers and antioxidants

Galata Chemicals liquid phosphite stabilizers serve as secondary antioxidants and processing stabilizers in polyolefins, PVC and engineering thermoplastics. They decompose hydroperoxides during high temperature melt compounding, preserving molecular weight and color integrity.

  • High purity liquid phosphite antioxidant chelators for thermoplastic polymers
  • Strong synergy with primary phenolic antioxidants and mixed metal stabilizers
  • Prevention of yellowing and degradation in polyethylene and polypropylene resin
  • Liquid physical form enables accurate automated dosing in compounding extruders

Identification of Galata Chemicals additives and catalyst grades

Technical selection of Galata Chemicals specialty additives requires verified parameters from product documentation. Inquiries should specify exact product grade codes such as FOMREZ SUL-4, UL-28, MARK 1900, DRAPEX 39 or BLENDEX 338 alongside chemical foundation and polymer resin matrices.

Submitting safety data sheets (SDS) and technical data sheets (TDS) ensures exact matching of active contents, tin concentrations, density and solvent types across industrial production lots.

Selection of FOMREZ organotin catalysts for polyurethane polymers

Selecting FOMREZ organotin catalysts depends on gelation kinetics and moisture sensitivity in polyurethane systems. For flexible and rigid polyurethane foams, dibutyltin dilaurate and thioglycolates (FOMREZ SUL-4, UL-1) promote rapid urethane reactions without excessive bubbling.

In moisture curing silane-terminated polymers and structural adhesives, FOMREZ UL-28 and UL-22 offer balanced hydrolytic stability under controlled plant conditions.

Application of MARK heat stabilizers in rigid and flexible PVC

MARK organotin and mixed metal heat stabilizers are selected according to thermal processing profiles and finished profile requirements.

For high output extrusion of rigid PVC window profiles, siding and pressure pipe, liquid organotin mercaptides (MARK 1900, MARK 1984) prevent thermal degradation above 190 degrees Celsius.

In flexible calendered vinyl sheets and wire insulation, calcium-zinc and barium-zinc formulas avoid plate-out on metal rolls.

Formulating DRAPEX epoxidized vegetable oil secondary plasticizers

DRAPEX epoxidized soybean oil (ESBO) and linseed oil (ELO) serve as secondary plasticizers and cost-effective thermal co-stabilizers in PVC formulations. Due to high oxirane oxygen content, DRAPEX 39 and DRAPEX 392 scavenge liberated hydrogen chloride during melt compounding.

When blended with MARK mixed metal systems, DRAPEX additives deliver synergistic performance, lowering primary stabilizer requirements while satisfying food contact regulations.

Upgrading impact strength and melt rheology with BLENDEX modifiers

BLENDEX polymer modifiers are compounded into rigid vinyl, engineering thermoplastics and alloy blends to optimize rheology and toughness. Ultra-high molecular weight acrylic processing aids (BLENDEX SA 100, SA 153) improve melt strength in cellular sheet extrusion, preventing cell collapse.

For low temperature ductility, core-shell modifiers BLENDEX 338 and SS 308 increase impact resistance, while BLENDEX 5470 enhances heat distortion temperature without sacrificing flow.

Incoming quality inspection and manufacturer COA verification

Every industrial delivery of Galata Chemicals additives is shipped in factory sealed containers: 190 to 200 kg steel drums, 20 to 25 kg pails or bulk IBC containers.

Shipments include a manufacturer Certificate of Analysis (COA) confirming batch lot numbers, production dates and laboratory test results. Receiving quality checks inspect appearance, Gardner color, kinematic viscosity at 25 degrees Celsius, density and oxirane values before production release.
