Product Description
EP Short Cut Fiber 2D*6MM Silane Treated Chopped Fiber for Epoxy Resin Reinforcement
EP chopped fiber 2D*6MM
Specifications can be customized
Product Overview
Our 2D*6MM EP Short Cut Fiber is a dedicated reinforcing short fiber specially developed for epoxy resin modification. With precise 2 denier fineness and fixed 6mm cutting length, equipped with epoxy-targeted silane surface modification, this fiber is an ideal functional filler to enhance comprehensive performance of all kinds of epoxy systems.
Many ordinary short fibers have poor compatibility with epoxy resin. After stirring, fibers are easy to separate and float, resulting in uneven strength and rough surface of finished epoxy products. Our EP short cut fiber solves this point thoroughly via professional surface treatment. The silane coupling agent on fiber surface builds a stable connection bridge between fiber and epoxy molecular chain, realizing uniform fusion and reliable force transmission inside composites.
When mixed into epoxy resin, the short fibers are evenly dispersed to form a dense interlaced network structure. During epoxy curing, it can effectively offset curing shrinkage stress, greatly reduce the risk of surface and internal cracking of castings. Meanwhile, the finished parts own higher impact resistance, bending strength and dimensional stability.
The 2D fine denier brings smooth surface effect for epoxy products. The 6mm length balances dispersion performance and reinforcement capacity. The fiber shows low fuzz during feeding and stirring, creating cleaner production environment. It can be widely used in epoxy casting, electronic encapsulation, epoxy repair mortar, insulating material and epoxy composite production.
Made from virgin raw materials with standardized production flow. Every batch undergoes strict quality inspection. Customization of fiber length, fineness and surface treatment scheme is acceptable according to customers' epoxy formulation and production technology.
Factory direct supply with sufficient inventory. Free test samples are available for formula trial, stirring dispersion test and finished product performance testing. We provide stable supply service for global epoxy composite factories, electronic material manufacturers and engineering material enterprises.

Core Advantages
Custom Silane Surface Treatment, Perfect Compatibility with Epoxy Resin
The fiber surface is modified by dedicated silane coupling agent, forming stable combination between fiber and epoxy matrix. Greatly enhance interface adhesion, avoid fiber floating, delamination and poor fusion defects. Effectively improve tensile strength, flexural strength and impact resistance of finished epoxy products.
2D Fine Denier + 6mm Precise Cutting, Excellent Uniform Dispersion
Strict cutting process ensures consistent fiber length. 2D fine denier can be evenly scattered inside epoxy resin without agglomeration and fiber balls. The surface of molded epoxy parts is smooth without particle protrusions, suitable for high-precision epoxy product manufacturing.
Low Fuzz & Stable Processing Performance
Adopt special spinning and cutting technology. Less broken fibers during mixing and stirring processes, reduce workshop flying lint. No frequent blockage of mixing equipment, support continuous large-scale production and improve production efficiency.
Anti-Aging & Chemical Resistance
Stable molecular structure, excellent resistance to acid, alkali and general chemical solvents. It will not degrade easily in long-term service, maintain the reinforcing effect of epoxy products, extend service life of composite components.
Significantly Improve Crack Resistance of Epoxy Products
Form three-dimensional support network inside epoxy resin, inhibit internal crack expansion caused by thermal stress and curing shrinkage. Solve common problems such as shrinkage cracking of epoxy castings and repair mortar.
Frequently Asked Questions
Q1: Why is this fiber named EP short cut fiber?
A1: EP represents epoxy resin. This short fiber adopts special surface modification design, which is specially optimized for epoxy (EP) resin system, and has far better compatibility than ordinary short fibers.
Q2: Can this short fiber prevent epoxy casting cracking?
A2: Yes. The interwoven fiber network can relieve curing shrinkage stress of epoxy, effectively inhibit crack generation and expansion, widely used for anti-crack modification of epoxy mortar and epoxy casting.
Q3: Will the fiber agglomerate when mixed into epoxy resin?
A3: With matched silane surface treatment and 2D fine denier design, the fiber has excellent dispersion. Normal low-speed stirring can achieve uniform distribution without fiber balls.
Q4: What mixing proportion is recommended for epoxy resin?
A4: The recommended addition ratio ranges from 1% to 5%. Customers can adjust the dosage according to target hardness, toughness and surface requirements of finished products.
Q5: What storage requirements does the fiber have?
A5: Please keep sealed and store in dry and ventilated warehouse, avoid long-term damp environment, to guarantee the surface treatment effect.
Q6: Can I get free samples for testing?
A6: Small test samples are provided free of charge for formulation experiment and performance verification (shipping cost collected).
