Q1: What is the primary function of TONSIL CO 636G L in polymer processing?
A: TONSIL CO 636G L is a highly active, low-ash clay-based catalyst designed to promote controlled crosslinking and thermal stabilization in peroxide-cured elastomers and thermoplastic vulcanizates (TPVs), particularly enhancing scorch safety and cure efficiency.
Q2: Is TONSIL CO 636G L compatible with silicone or fluoropolymer systems?
A: It is primarily formulated for use in non-polar and semi-crystalline thermoplastics and elastomers—such as EPDM, PP-based TPVs, and certain polyolefin blends. Compatibility with high-performance polymers like silicones or fluoropolymers is not typical and requires prior compatibility testing under application-specific conditions.
Q3: How should TONSIL CO 636G L be incorporated into a compound?
A: It is typically added during the masterbatch or final mixing stage using standard internal mixers or twin-screw extruders. Good dispersion is essential, and it is generally used at low concentrations—dosage depends on formulation requirements but commonly ranges from 0.1% to 2% by weight relative to the base polymer.
Q4: Does this catalyst require special handling or storage conditions?
A: Yes. As a fine, hygroscopic powder, TONSIL CO 636G L should be stored in a cool, dry environment under sealed conditions to prevent moisture uptake and agglomeration. Avoid exposure to high humidity or direct sunlight during handling and storage.
