Product Features and Performance
UL94-V0 flame retardancy (LOI≥33%) effectively restrains cable related fire spread, delivering reliable fire safety for power, rail transit and chemical industry infrastructure.
30±2% high glass fiber loading brings ultra high tensile, flexural and impact performance, protecting cable housings against heavy squeezing and mechanical damage in buried, tunnel and wet corrosive environments.
Low molding shrinkage guarantees high dimensional accuracy, enabling tight housing fit and consistent sealing performance for field installation.
Low water absorption with stable insulation, acid alkali and anti aging properties; free from electrochemical corrosion for long term underground or tunnel service without rusting.
Supports one shot integral molding for lightweight metal replacement. Backed by in house mass production lines to ensure stable bulk supply for large scale infrastructure projects.
Applications
It is widely applied to cable protection boxes, cable joint boxes and cable branch housings for municipal power grids, rail transit, utility tunnels, photovoltaic power stations and chemical parks. Suitable for direct burial, tunnels, underground, humid and corrosive environments, providing protection, insulation, flame resistance and anti-damage performance for cable joints.
Manufacturing and Supply Support
LANTAI’s SMC product system is supported by real production and molding capability rather than conceptual presentation. With 3 SMC lines and 15 molding machines ranging from 315T to 2500T, LANTAI can support both regular industrial projects and higher-requirement structural applications. For buyers who need stable bulk supply and reliable project delivery, this manufacturing base provides stronger support for consistency and execution efficiency.
From material development to bulk delivery, LANTAI’s SMC system is supported by laboratory capability, process control, and testing procedures. For buyers who care about specification stability, batch consistency, and project control, this quality and R&D support provides stronger confidence for both evaluation and long-term sourcing.
