Methyl-tin PVC Stabilizer YC-181

Chemical Name: Methyl-tin Mercaptide
Chemical Formula: C31H60O6S3Sn/C22H44O4S2Sn
CAS No.: 57583-35-4
Sn content: 19.2%

>>Methyl-tin PVC stabilizer is plastic heat stabilizer that is highly effective for the calendering, extrusion, injection molding and blow molding of rigid polyvinyl chloride (PVC). Due to its high safety profile, it’s particularly suitable for food packaging and high-clarity rigid PVC products such as transparent sheets, boards and shrink films. It’s also widely used in plastic doors and windows, water pipes and decorative materials, serving as a safer alternative to other highly toxic plastic heat stabilizers.

Butyl-tin PVC Stabilizer YC-108

Chemical Name: Butyl-tin Mercaptide
Chemical Formula: (C4H9)2Sn(SCH2COOC8H17)2
CAS No.: 26410-42-4
Sn content: 18.5%

>>Butyl-tin PVC stabilizer is a type of organotin compound added to polyvinyl chloride (PVC) to protect it from heat and weathering during processing and in the finished product. These stabilizers, which also include butyl tin carboxylates and butyl tin mercaptides, are valued for their high transparency, excellent heat and light stability, and compatibility with other PVC additives. They are particularly useful in rigid PVC applications like transparent films, sheets, and various molded and extruded products.

Monobutyltin Trichloride MBTC-99

Chemical Name: Monobutyltin Trichloride (MBTC)
Chemical Formula: C4H9SnCl3
CAS No.: 1118-46-3
Sn content: 41%

>>Monobutyltin trichloride is one of the organotin compounds and is also abbreviated as MBTC or MBTCl. At room temperature it is a clear to yellowish liquid, not very volatile and soluble in water and organic solvents. The most important area of application is in the coating of glass, but monobutyltin trichloride is also used as a catalyst and stabilizer. The substance is also an intermediate from which numerous other organotin compounds are produced, such as di- and tributyltin catalysts for esterification and transesterification reactions.

Antimony Stabilizer YC-AT168

Chemical Name: Antimony Mercaptide Stabilizer
Chemical Formula: Sb(SCH2COOC8H17)3
Appearance: Yellowish Liquid
Antimony Content: 16.5%

>>Antimony stabilizer are unbeatable in terms of stability, color, transparency of the final product, and processing window. However, we should also be aware that they have some disadvantages compared to tin-free alternatives regarding weathering. Antimony mercaptides are either not suitable or only conditionally suitable for outdoor applications, as they are highly likely to cause greying in the presence of small amounts of titanium dioxide.

Liquid Barium Zinc Stabilizer YC-106

Chemical Name: Ba/Zn Stabilizer
Appearance: Yellowish Liquid
Barium Content: 6.5%
Zinc Content: 1.8%

>>Liquid Ba/Zn stabilizer is a light red or yellow transparent liquid. It is a high-efficiency stabilizer with excellent transparency and coloring, high-efficiency self-gliding and extremely long thermal stability. It is mainly suitable for the processing of various environmentally friendly soft and semi-soft PVC products, especially for high-transparency products such as PVC super-transparent films, crystal shoes, tablecloths, etc.

Solid Ca/Zn PVC Stabilizer

Chemical Name: Ca/Zn Stabilizer YC-6801/6802/6811/6812/6821/6831/6861/6881
Appearance: White Powder
Ca/Zn Content: 2.5%~8.5%
Ref. Dosage: 2.5%~5.5%

>>Solid Ca/Zn stabilizers, usually in powder form, are among the most widely used lead-free, non-toxic and environmentally friendly PVC stabilizers. They are based on a combination of calcium and zinc soaps, and provide high thermal stability and lubricity when used with both organic and inorganic co-stabilizers, making them suitable for a wide range of processing conditions. These stabilizers are primarily used for soft, semi-rigid and rigid PVC applications, including PVC films, sheets, shoes, profiles, pipes, wires, hoses and plastic injection and extrusion materials.
