1. How important is it to follow MTPlastech general recommendations on product usage? up

Very.Mtplastech recommendations for the storage, installation and general treatment of products are drafted to ensure that the product’s quality and serviceability is met to full extent, and following these recommendation ensures that product warranty is valid.

2. How long do MTPlastech Sheets last? up

MTplastech supplies individual product warranties against most types of failures. The life expectancy can be as much as 10 years, depending on professional installation practice and environmental factors like air pollution, winds, and erosion by sand particles.

3. How do I cut these sheets? up

Easily. MTplastech sheets may be cut with either a circular saw (using a very fine blade, e.g. plywood, etc.) or a jig saw. For best results it is often better to cut a few sheets at a time to reduce vibration. Also, if using a toothed circular saw blade, better results may be seen running the blade backwards. Sheets may also be cut by hand by carefully using tin snips or a utility knife. For further information please refer to our product manuals.

4. What should I use to clean my panels? up

Warm water with a mild household detergent should be sufficient to clean panels. Wipe off any remained dirt with a soft cloth and wash again. NEVER use a solvent based cleaner (ammonia, etc.). AVOID using sponges or brushes that can scratch the panels surface.

5. My building inspector says I need to know your flame spread rating.Can you provide this information? up

Yes. We can provide test reports and other such documents. Please contact your MTplastech dealer if you require these data.

6. How should I store packed sheets? up

Store in a protected, shaded, ventilated site, with no direct exposure to sunlight and winds. In outdoor temporary storage cover with opaque protective film, and avoid PVC films and heat-absorbing materials. Please note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet.

7. Why are there polyethylene films on certain sheets and should I peel it off? up

The surface films in certain sheets, are needed for protection against dirt and scratching, and also used to carry important information to the installer and final customer. It is recommended to peel off the protective films only after installation. Please note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet.

8. Can the sheets be curved? up

Yes. Sheets can be curved and serve in many shapes, provided the relevant MTplastech specifications for minimum radius in curving are followed.

9. Can these sheets catch fire? up

Yes. In principle all plastic materials are flammable, and will catch fire in presence of exterior flame.

10. Do the sheets expand in heat? up

Yes. Plastic sheets expand with heat, and shrink with cold. As engineering plastics, PC and PVC demonstrate limited expansion/contraction Vs other plastics, however this change in dimensions should be considered.
