What is ECR glass?

Traditional E-glass is a kind of  "electronic" glass with good water-resistance, insulation, and high mechanical strength. To simplify the E-glass production, manufacturers add B2O3 and fluorine in the glass batch. Therefore particles containing B2O3 and volatile of fluorine are released into the atmosphere during the glass melting process. To reduce environment pollution, ECR glass comes into being.

ECR Glass Advantage

1. Environmentally friendly ECR glass is similar to E-glass but without boron and fluorine.
2. Due to the removal of B2O3 and fluorine in the glass formulation, the chemical resistance (including water-resistance, acid-resistance and alkali-resistance) is greatly improved - especially its acid-resistance.
3. Higher temperature resistance because the softening point of ECR glass is 40-500 degrees C higher than E-glass
4. ECR Glass has better dielectric strength, lower electrical leakage, and higher surface resistance.
5. ECR glass shows better mechanical properties when compared with E-glass
6. ECR glass is suitable for all the applications that E-glass suits, except that it is not suitable for transparent FRP panel applications
7. ECR glass is produced under the standard of ASTM-D578-1999 since January 2005.

Outstanding Features In Some Applications Over E-Glass

Thermosetting Matrix Systems

• FRP pipe: Compared with E-glass the FRP pipe made from ECR glass enjoys better acid resistance. In many countries, especially in Middle East countries, the sewage pipes must be made with ECR glass or by OC's advantex glass fiber
• Marine: Compared with E-glass, some FRP products mainly made with ECR Glass (such as Chopped Strands Mat, Woven Roving, and Spray-up roving) enjoy better seawater resistance in marine applications made with these ECR materials.
• Rich resin FRP field such as the liners of FRP pipes, acid resistant storage tank mainly use surface veil ,chopped strand mat, woven roving and combo mat.
• Pultrusion FRP products: pultrusion products made by ECR glass enjoy better acid resistance, insulation, tensile strength and modulus. Acid-resistant epoxy insulation rod must be made by ECR glass or OC's Advantex glass fiber.

Thermoplastic Matrix Systems

• Lower harmful heavy metal volume than E-glass. Chopped strands, direct roving and multi-end roving made with ECR glass are therefore better for usage in cars, electronics, and electronic appliances.
• FRTP products enjoy a higher modulus than E-glass.
• Others: The softening point of ECR glass is higher than E-glass, so it is more suitable for the high temperature resistance products, such as muffler for cars

ECR Spray Up Roving - ECR-10K
	ECR-10K spray up roving is made of standard ECR-glass multi-end fiberglass Designed for use in polyester and vinyl ester resin spray up systems Ideal for producing consumer products, corrosion and construction applications Can be used for filament winding process to make pipes and tanks.
Outstanding Process Properties High performance sizing, very low static, fuzz, and fiber fly Excellent chop ability, uniform glass dispersion, and lay down properties Ease of rollout and air release, excellent mold conformance Outstanding roving pay-out and package transfer Rapid wet-through, fast and complete wet-out High Laminate Properties High laminate mechanical properties and wet strength retention For general polyester and vinyl ester resin, exhibit mechanical properties equal or better than E-glass roving Strong bonding between the glass fibers and the resin matrix due to the special designed sizing. The finished laminate has high wet strength retention because the laminate has high level resistance to hydrolytic attack. Corrosion Resistance The final product made with ECR-10K roving has better acid and strain corrosion resistance than E-glass ECR-10K is the preferred choice over E-glass for sewer GRP pipe and chemical resistance applications The long-term strength retention or ECR-10K is significantly higher thank E-glass.
