PUREstab 1076

PUREstab 1076 is a sterically hindered phenolic antioxidant. It is a highly efficient and non-discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. PUREstab 1076 is odorless, stable to light and has good compatibility with most substrates, low volatility and high resistance to extraction.

Features & Benefits

PUREstab 1076 can be used in combination with other additives such as co-stabilizers, e.g. thioethers (long term heat stabilizers), phosphites, phosphonites (secondary antioxidant), light stabilizers and other functional stabilizers. It is of particular interest to mention the enhanced effectiveness obtained by combining PUREstab 1076 with PUREfos 168.

Applications & Uses

Compatible Polymers & Resins
Styrene Copolymers
Applications

At concentrations of 0.05% - 0.2%, PUREstab 1076 is providing long-term thermal stability to the polymer. In polyolefins the recommended concentration levels range between 0.1% and 0.4% depending on the matrix, processing conditions and longterm thermal stability requirements. For styrene homo- and copolymers it is ranging from 0.1 to 0.3%, in hot melt adhesives, from 0.2% to 1.0%, in synthetic tackifier resins, from 0.1% to 0.5%.

Guidelines for Use

At concentrations of 0.05% - 0.2%, PUREstab 1076 is providing long-term thermal stability to the polymer. Nevertheless, concentrations up to several percent may be suitable depending on the requirement of the end application and the substrate to be stabilized.

In polyolefins the recommended concentration levels of PUREstab 1076 range between 0.1% and 0.4% depending on the matrix, processing conditions and longterm thermal stability requirements. The optimum level has to be determined depending on the application requirement.

The concentration levels of PUREstab 1076 recommended:

  • for styrene homo- and copolymers is ranging from 0.1 to 0.3%
  • in hot melt adhesives it is ranging from 0.2% to 1.0%,
  • in synthetic tackifier resins it is ranging from 0.1% and 0.5%.
