What Are Plastic H Channel Extrusions?

Anytime you see a price tag hanging precariously beneath your favorite at of spaghetti sauce at the grocery store, you’re most likely looking at a plastic h channel keeping that price tag affixed.

The plastic h-channel extrusion is sometimes called the “joiner” channel because it joins the panels of different materials. It can connect plywood, Foamex, surrogate, and a variety of other materials.

The h-channel can be ordered as both a stock plastic extrusion or a custom plastic extrusion. The plastic extrusion process produces a variety of plastic materials. H channel plastic is special because it is shaped like an H.

How Plastic Extrusion Works

The plastic extrusion process starts with a mass of raw plastic in a hopper hanging above a closed channel. The hopper drops the plastic materials into the channel.

Inside the channel is a long screw. The plastic pieces rub against each other as the screw moves them through the channel. The friction along with some external heat causes the plastic to melt into a liquid.

Once the plastic has reached the end of the channel, it is molten plastic and ready for a die. A die is a special tool at the end of the channel that shapes raw materials like plastic into a product like the plastic h channel.

The die is a metal plate cute that has a hole cut in it. The plastic goes through the hole and is shaped into a specific shape. At the end of the die, the plastic comes out as the new, extruded plastic

Then the plastic cools and hardens. Machines cut and prepare the new plastic material, preparing it for shipping or more processing.

We use the highest quality of PETG Copolymer (Polyethylene Terephthalate Glycol), Clear Tenite CAP, and Tenite CAB plastic. While these are our specialty, we use other materials as well.

Typical plastic h channel extrusions consist of a variety of different materials. These are some of those materials and how they’re used.

  • PVC: PVC comes in both firm and flexible grades, clear and opaque. It holds its shape well and yet contours to curved surface areas. It has the best impact strength of all plastics and thus people use it both inside and outside for things like gaskets, edge trims, and retention clips.
  • Polycarbonate or PC: You typically see PC used when you need a high-impact resistance material. It has a smooth surface quality as well as colorability. Thus we typically see it used for corner protectors, edge trims, and pricing channels.
  • ABS or Acrylonitrile Butadiene Styrene: ABS is a high-impact resistance material that colors well. It has a smooth surface, and we see it most often inside rather than outside.
  • Polyethylene (PE0) and Polypropylene (PP): PE is one of the more flexible plastic while PP is the more rigid of these two poly materials. It works best in situations that do not require UV resistance, so we see it in places like bag closure clips, edge trims, assembly magazines, pool liner clips, and wire covers.
  • Acrylics: Acrylics work best in situations where clarity and economics are high priority. So you see it with price channels and price tag holders along with bin edging, hinge applications, and shelving edging. It does not absorb impact well.
