DFM-103 Blend Polyols

Products Introduction
Imitate wood foam, is a new type of carving synthetic materials. It has high mechanical strength and rigidity, simple molding process , high production efficiency, good appearance.
Characteristics are as follows :
1. excellent repetition molding property. It not only can mould certain shape size, but also mould lifelike wood texture and other designs, good feel of touch
2. appearance and feel close to wood , which could be planed, nailed, drilled, and carved patterns or designs .
3. mould can only be produced using aluminum or steel, but can use silicon rubber, epoxy resin or other resin, which are low cost and easy machining.
4. molding process is simple, fast, high efficiency of qualified.
5. physical and mechanical properties is one of optimal synthesis wood produced by various polymer . Physical property can be controled by adjusting the formula.
