Polymers (Plastic) Benefits

Each polymer we supply has its own unique benefits, but in general, our plastic polymers are advantageous for their:

  • Strength and resistance capabilities. Polymers are quite strong and durable. Depending on their makeup, polymer plastics can have resistance properties to protect them against wear and abrasion, extreme or fluctuating temperatures, moisture, corrosion, and UV light or radiation.
  • Light weight. Compared to more traditional options, plastic polymers are much lighter materials and so result in lightweight parts. Such parts lessen the structural load in construction applications, improve vehicles’ fuel efficiency in the automotive sector, and more.
  • Manufacturability. Polymer plastics are easy to work with and shape, making them compatible with multiple production methods such as injection molding.
  • Design flexibility. Also, these materials support greater flexibility of design for making innovative, high-performance products. Manufacturers can use polymers to generate intricately detailed parts in complex or unique shapes that traditional materials might not be able to achieve.
  • Affordability. These materials also lend themselves to large-scale manufacturing due to their affordability. Not only are they more economical to produce than metal, glass, or other standard materials, but they enable manufacturers to generate cost-effective parts and products.

Polymers (Plastic) Applications

An additional advantage of polymer plastics is their impressive versatility, as they’re compatible with a range of industries and projects. These materials are ideal for the following applications:

  • Piping systems. Polyvinyl chloride (PVC) pipes consist of polymers, and they have common applications in supplying or draining water as well as irrigation. PVC piping systems are resistant to corrosion and leaks, and they’re lighter than their copper alternatives.
  • Insulation. As certain varieties are electrically insulative, polymers have widespread uses providing insulation for wiring, cables, circuit boards, and electronic device housings or enclosures.
  • Roofing. Buildings often utilize polymers for their roofing membranes or as a substitute for standard shingles. Polymer roofing products offer long-lasting performance and protection against weathering.
  • Flooring. The composition of vinyl flooring includes polymer-based plastics, resulting in a flooring option that’s both durable and resistant to wear and water.
  • Coatings, paints, sealants, and adhesives. Polymer-based coatings and paints are effective in enhancing the surface appearance of a part while safeguarding it against wear, moisture, and fading. In sealants and adhesives, polymer materials help bond components and form water- and airtight seals.
  • Medical devices. Polymers even have applications in the healthcare sector, serving as ideal materials for catheters, syringes, prosthetics, and biocompatible implants safe for use in the human body.
