Brief Introduction

LE-8217F is a modified BPA (bisphenol A) epoxy resin, paired with LH-8217F, a liquid modified carboxylic anhydride hardener. This system is designed for applications requiring precise dimensional stability in electric insulators.

Applications

This epoxy resin is suitable for medium and high voltage electrical insulators, including various insulators, transformers, and insulation products.

Processing Methods

Processing can be accomplished using a conventional gravity casting method under vacuum or through an Automatic Pressure Gelation (APG) process. The production methods can be customized to meet the client's existing manufacturing practices.

Properties

This two-component system is a saturated cyclic epoxy resin without pre-mixed fillers, remaining in liquid form at room temperature. It features low curing shrinkage, ensuring good dimensional stability, excellent processing characteristics, and superior mechanical and electrical properties.
