Product Information for PVC

Sintra® PVC Plastic is only ONE of the many types of plastics available.

We've been providing rigid, Sintra Plastic Signs for almost 30 years so I have some worthy insights to share.

Air is one of the main ingredients!  
The sign industry refers to this material as "Foamed PVC Plastic". Air is injected into the hot molten plastic liquid creating a hot foam mixture that hardens into a sheet, when cooled.

All that air is what makes this plastic lightweight, which is great for all sorts of applications - just not outside.  PVC Plastic is NOT recommended for outdoor use because it is not a UV stable plastic.  Yet many sign companies still sell PVC Signs for outdoor use which ends up warping.  The thermal heat radiated from the sun causes the plastic to EXPAND and contract.  All that movement, day after day in the sun, causes distortions in the plastic. 

There are far better solar-grade sign materials to use outdoors, that cost the same.

When you need a standard indoor plastic sign for everyday use, here are some of the most popular applications:

  • Retail & Display Signs
  • Business & Office Signs
  • Warehouse & Factory Signs
  • LEAN Manufacturing Signs
  • Safety Signs
  • Point-of-Purchase Signs
  • Sale & Promotional Signs
  • Identification Signs
  • Trade Show Signage
  • Hanging Signs
  • Directional Signs

However, you are not limited to just these uses. Whatever your indoor signage needs are, standard Sintra plastic provides a durable, cost-effective option.

If you are looking for an outdoor sign, I recommend Alumalite, ARMOUR-Wood, Coroplast, Dibond, Aluminum or Dura-Wood materials instead.

What are the most important ingredients of this Indoor Sign Material:

  • Surface - The material itself looks good!  The surface looks smooth and is smooth, to the touch.
  • Finish - Some people say the finish looks flat. To me, it looks more like a satin finish.  It's definitely NOT high gloss! cool
  • Durable - This is not a fragile material. It CAN break. But it's plenty strong enough for everyday use.
  • Lightweight - Yes, this material is lightweight, but standard Aluminum and Dibond signs, are even lighter.
  • Waterproof - This type of plastic is unaffected by moisture or water (not to mistaken as weatherproof).
  • Easy - Installation is easy, especially with our convenient mounting accessories.

Mounting accessories include matching screws, double-sided tape, suction cups, S-hooks, ceiling chains and our blind fastener system.  

For yard signs, real estate signs or any other outdoor signage, we recommend outdoor grade sign materials.

It's not just the Quality of the Sign Ingredients ... it's how they are put together that matters!
