Considerations To Select A TPE Material

Almost new TPEs are developed regularly. There are many reasons TPE material suppliers offer new polymer technologies, evolving the preference of customers. According to your requirements, you may know if you require a TPV or an SBC compound. To match the wide range of performance requirements, TPEs can be custom-made. Here is a guide to selecting the best TPE material.

Material Replacement Or New Grade:

It is vital to understand what material to use. For instance, silicone rubber or PVC, or other TPEs where improvements are required. Seek any functional and performance requirements if there are any brand new applications for TPE.

TPE Material Manufacturing Process :

Consider how the part will be assembled and manufactured. Based on how the material is processed, the formulations of TPE are adjusted. Also, it can be custom-made for extrusion, injection molding, or blow molding.

TPR material suppliers also provide many customization options to get the best possible product.

High-flow TPEs are developed for complex parts using thin and thick sections or severe undercuts. It is important to know the substrate material if the TPE is over-molded or co-extruded.

Cost targets:

Mostly, there are cost targets involved in the selection of material. These are defined as cost per pound or the cost per part. Even having a proper estimate in mind will help in the decision-making.

Market And Industry:

If you are designing a pipe seal or a medical device, there are some rules and regulations to follow, depending on the industry. You may also require certifications and extra texting and may impact the choice of ingredients used. You must consider the following things:

  • Electrical wire and cable
  • Automotive
  • Customer products, housewares, and toys
  • Healthcare and medical
  • Construction and building

Conditions of Environment:

First, know whether you will use the products indoor, outdoor, or both. Know what temperatures it will be exposed to and if it can be used in the seal. Consider the following conditions:

  • Temperature requirements
  • UV exposure
  • Chemical exposure
  • Usage

Surface Appearance And Aesthetics:

TPEs are custom-made to meet particular requirements. TPE are categorized by their feel, color, and finish. These give a feel of high surface friction to the touch or silky-smooth or lubricious. They are available in translucent, Plexiglas, or opaque and can also be provided in custom colors. It gives a surface finish of matte or glossy.

Performance Of Material:

The thermal and physical properties of TPEs are directly related to their composition and also the manufacturing method. If there are particular requirements, you must evaluate them in the process of material selection. Consider the following factors:

  • Hardness
  • Stretch and bounce back
  • Compression set
  • Abrasion resistance
  • Tear strength
  • Resistance of bending
  • Adhesion to other materials
  • Special requirements
