- No added formaldehyde (exceeds CARB standards), MDI adhesive is free of formaldehyde and other harmful volatile organic compounds.
- 100% degradable or recyclable to an equal product.
- Lower density reduces tool and machine wear
- Panel rigidity improves door stability
- Increases door fire resistance (compared to hollow core)
- Easily processed, improving yield and reducing losses
- Two sheets of door core can be made into five doors which offer a super cost advantage
- Can be pasted directly with wood skin which reduces the quantity of surface decoration
- Much lighter and better strength than normal door
