Application

TMG 234 is useful for the following applications:
• Esterification and transesterification catalyst
• Condensation catalyst for silanemodified polymers
• Stabilizer for PVC
• Use as heat stabilizer for ABS/PVC alloys, recommended concentration: 0.03-1 %.
• Use as heat stabilizer for flame retardant versions of ABS, especially when halogenated flame retardants like hexabromocylododecane and similar products are used,recommended concentration: 0.1 – 1%
• Use in ABS / PTFE blends with flame retardant properties
• Use as coupling agent for glass-fibre reinforced thermoplastic ABS, TMG 234 improves the notched impact strength
• Use as dispersant for TiO2 in ABS
TMG 234 distinguishes by its especially high purity. The content of volatiles is very low.
