Mitsui MILEX™ XL-225MB Phenol Aralkyl Resin, Standard Grade

Subcategory: Phenolic; Thermoset

Material Notes:
The MILEX™ Family of products is widely featured in brake systems of automobiles made by the top automakers through Mitsui Chemicals' affiliation with leading brake manufacturers. The phenolic material is primarily used as binders in brake pad and clutch facing disc friction materials. The advantage of incorporating the MILEX material into a brake design is that the material provides a non-abrasive, vibratory free surface finish, which is very important in the performance of the brake system. Additionally, its superior performance at elevated temperatures and excellent moldability aids in brake noise reduction.

The XL series is composed of phenol aralkyl resins, of which there are three different grade levels. The XL line is known for its stable friction and abrasion, excellent heat and chemical resistance and anti-noise and vibratory qualities. In automotive applications, it is used in brake pads due to its stable friction and low abrasion. In electrical applications, the material is used as a molding compound that yields excellent heat and moisture resistant electrical insulation.

Applications:

• Automotive friction materials (brake pads, clutch facing discs, etc)
• Epoxy resin hardener for electronic materials
• Additive to improve heat resistance of thermoplastics
• Adhesives, especially with elastomers, to bond to metal
