-WB-222 is a highly concentrated, water free mixture of high-molecular weight, aliphatic, fatty acid esters and condensation products.
Pastille, Bead or Powder
- STRUKTOL® WB 222 is a processing additive for rubber polymers used to improve the general compound processing
- It is found to shorten the mixing time by faster filler incorporation.
- STRUKTOL® WB 222 prevents sticking of elastomers and compounds to rotors and rolls.
- It is found useful in reducing the risk of scorching particularly in highly loaded compounds. Due to the good plasticizing properties of STRUKTOL® WB 222, molds can be filled faster with lower pressures during injection and transfer molding. Mold release is improved.
- STRUKTOL® WB 222 greatly improves filler dispersion, as well as flow properties and release during processing, and demolding especially in nitrile compounds.
- 0.5 to 2% of the total batch weight
At least 2 years when stored under normal storage conditions
