Application :
ECR-469L roving is continuous and single-end
roving made of standard ECR-glass.Mainly utilized in filament winding
and weaving process.ECR-469L roving is designed for composite requires
maximum wet-out and wet-out consistency.ECR-469L is compatible with
polyester, vinyl ester and epoxy resin systems. For epoxy resin systems,
it's just recommended for general-purpose applications.
Properties :
Outstanding process properties
1.Stable roving density.
2.Excellent abrasion resistance,lower fuzz and on sizing deposit on
contact point.
3.Zero catenary,easily opened strands.
4.Low resin demand during process.
5.Excellent package transfer.
High laminate properties :
1.High laminate mechanical properties and wet strength retention.
2.For general polyester and vinyl ester resins,exhibit mechannical
properties equal or better than E-glass roving.
3.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 :
1.The final product used ECR-469L has superior acid and strain
corrosion resistance than E-glass.
2.ECR-469L is the preferred choice over E-glass for sewer GRP pipe and
chemical resistance applications.
3.The long-term strength retention or ECR-469L is significantly higher.
