SperseStab™ 4866 banner
Interspersal, Inc company logo
SperseStab™ 4866
  • Functions:Thermal Stabilizer, Stabilizer, Heat Stabilizer, Light Stabilizer
  • Labeling Claims:Non-Mutagenic, Not Listed In California Proposition 65, Non-Carcinogenic, Halogen-free
  • Compatible Polymers & Resins:Polyesters, Thermoplastic Polyurethane (TPU), Polyvinyl Chloride (PVC), Polyethers
  • Features:Radical Trapping, Excellent Solubility, Cost Effective, UV Absorbing, Long Term Photo-Permanence, Non-Interacting , Good Thermal Stability, Excellent UV Stability, Low Volatility, Thermal Resistance, Non-discoloring
SperseStab™ 4866 is ideally suited for both PVC and TPU systems, with strong UV-B absorbance as well as radical trapping ability that does not impart color under UV stability testing. Additionally, SperseStab™ 4866 includes a synergistic UV stabilizer for additional long-term UV stability. It can be used in conjunction with other thermal stabilizers and antioxidants.

SperseStab™ TNPP
  • Functions:Heat Stabilizer, Antioxidant, Stabilizer
  • Compatible Polymers & Resins:Nitrile Butadiene Rubber (NBR), Polystyrenes (PS), Polypropylenes (PP), Styrene Butadiene Styrene (SBS), Styrene Butadiene Rubber (SBR), Polyethylenes (PE)
  • Features:Low Migration, Cost Effective, Prevents Gel Formation, Good Thermal Stability, Non-Staining, Low Color Formation, Non-discoloring
  • Synonyms:Tris (4-Nonylphenyl)Phosphite, Tris(P-Nonylphenyl)Phosphite
SperseStab™ TNPP is a liquid phosphite antioxidant and thermal stabilizer for use in elastomers, including SBR, NBR, and SIS. It is highly effective in light-colored solutions and emulsion-polymerized elastomers. It is extremely efficient at preventing gel formation during polymerization, processing, and long-term heat aging. Additionally, this cost-effective process stabilizer finds application in thermoplastic polymers such as polyethylene, polypropylene, polystyrene, and ABS.

SperseStab™ 1425
  • Functions:Heat Stabilizer, Catalyst, Antioxidant, Stabilizer
  • Reaction Type:Transesterification
  • Labeling Claims:Non-Mutagenic, Non-Carcinogenic, Not Listed In California Proposition 65
  • Synonyms:Antioxidant 1425, Calcium (3,5-di-tert-butyl-4-hydroxybenzyl monoethyl phosphonate), Calcium bis(ethyl 3,5-di-tert-butyl-4-hydroxybenzylphosphonate), Calcium bis(monoethyl (3,5-di-tert-butyl-4-hydroxylbenzyl)phosphonate), Calcium bis[3,5-di(tert-butyl)-4-hydroxybenzyl(ethoxy)phosphinate], Calcium bis[ethyl (3,5-di-tert-butyl-4-hydroxyphenyl)methanephosphonate], Calcium bis[monoethyl (3,5-di-tert-butyl-4-hydroxybenzyl)phosphonate], Calcium diethyl bis[[[3,5-(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]phosphonate]
SperseStab™ 1425 is a high-molecular-weight phenolic antioxidant containing a phosphonate located para to the phenol. This orientation provides excellent color and low gas fading in a UV-stabilized antioxidant. The calcium salt acts as a soluble catalyst, especially for the esterification of rosin esters. Additionally, SperseStab™ 1425 works as a catalyst in the solid-state polymerization of PET polymers. Other applications include polyolefins, fibers, adhesives, and lubricating oils and greases.
