Product Features and Performance
UL94-V0 flame retardancy (LOI≥33%) enhances fire safety performance for hotel, cabin and prefabricated bathroom projects.
Low molding shrinkage ensures stable dimension, reduces warpage and delivers good fitting performance for shower bases and wall panels.
Ultra low water absorption prevents blistering and delamination under long term humid bathroom conditions, extending service life of bathtubs and sanitary parts.
Balanced mechanical strength offers good foot load & impact resistance, avoiding cracking in daily usage; maintains stability under continuous hot water contact.
Moldable to glossy/matte seamless curved surfaces, anti mold and corrosion resistant, cutting daily cleaning maintenance workload.
Integral compression molding realizes complex sanitary shapes. Supported by mass production capacity for stable bulk supply of prefabricated bathroom projects.

Applications
It is widely used for integrated bathroom components, including shower bases, bathtubs, shower wall panels and sink bases for prefabricated bathrooms. Applied in residential apartments, hotels, prefabricated cabins and construction projects, meeting requirements of waterproofing, durability and easy maintenance in long-term humid separated wet-dry bathroom environments.




Manufacturing and Supply Support
LANTAI’s SMC product system is supported by real production and molding capability rather than conceptual presentation.
