PP Hollow Plastic Formwork Advantages
1. PP Hollow Plastic Formwork Flame Retardant High Safety
-
PP Hollow Plastic Formwork Compliant with national Class B1 flame retardant standard, it features self-extinguishing performance, which prevents fire spreading and effectively reduces on-site fire risks to improve construction safety.
2. PP Hollow Plastic Formwork High Reuse Rate Cost Saving
-
PP Hollow Plastic Formwork It can be reused more than 50 times, and premium grade up to 100 times, far more durable than traditional wood and bamboo formwork. High recycling utilization greatly reduces project comprehensive cost and speeds up construction progress.
3. PP Hollow Plastic Formwork Waterproof Corrosion Resistant
-
PP Hollow Plastic Formwork Made of modified PP material with ultra-low water absorption, it is waterproof, acid and alkali resistant, mildew-proof and insect-proof. It maintains stable performance without deformation or cracking in humid and harsh environments.
4. PP Hollow Plastic Formwork Excellent Demolding Effect
-
PP Hollow Plastic Formwork Double-sided smooth panel ensures flat and smooth concrete surface. No release agent and no secondary repair or plastering required, saving plenty of labor, materials and time costs.
5. PP Hollow Plastic Formwork Lightweight Easy Construction
-
The hollow lightweight structure features light weight and high strength, easy for manual handling and installation. It can be freely cut, sawed and drilled, adapting to various special-shaped construction scenarios with high flexibility.
6. PP Hollow Plastic Formwork Eco-Friendly & 100% Recyclable
-
PP Hollow Plastic Formwork Non-toxic, odorless and formaldehyde-free with no construction dust pollution. Discarded formwork is 100% recyclable and produces no construction waste, fully meeting green building and low-carbon standards.
