Product Features and Performance
Higher glass fiber loading delivers superior tensile & flexural strength, greatly reducing warpage and deformation risk for large size, wide span and multi compartment boxes.
Good flow performance supports one piece molding of enclosures, mounting brackets and reinforcing ribs, helping you simplify mold design and cut tooling costs.
Low water absorption together with UV and acid alkali resistance ensures stable insulation and long service life under outdoor exposure, no delamination or cracking.
Reliable heat resistance and impact strength safeguard internal meters and valve assemblies against harsh outdoor conditions.
Non flame retardant formulation brings obvious cost benefits compared with V1/V0 grades, supported by our mass production capacity for consistent bulk supply for non fire mandated projects.
Applications
Suitable for large-size multi-compartment electricity meter boxes, floor-mounted gas control cabinets, large outdoor weak-current enclosures and electrical protection boxes in non-fire-risk industrial areas. Applied to civil and industrial outdoor projects without mandatory fire standards but requiring high rigidity and anti-deformation performance.
* Important note: This grade has no flame retardant property and cannot be used for enclosures requiring fire inspection approval.
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.
