Material

Below is a list of the materials in alphabetical order.

A-PET is a material known for its robustness; but also its shock-resistance is important, as well as its good resistance to internal pressure and stress-cracking. Moreover, it has good gas, UV and water barrier properties. It can be used at temperatures between -20°C to +60°C.

This material is useful for lids, salad trays... and other packaging that need to show the product (freshness, shape ...); Indeed, A-PET is skin and shows a transparency close to glass.

ABS is used for rigid objects because the material is very dimensionally stable. It is lightweight but hard and impact resistant. In addition, ABS has little tendency to creep *. Because ABS is a thermoplastic, the material cannot withstand high temperatures. The maximum temperature that the material can tolerate lies between 85°C and 100°C.

* Creep is the permanent deformation of a material that is stressed for a long time with a tension (tensile force, compressive force, bending). Creep is usually an undesirable phenomenon, and can be a limiting factor for the object’s lifetime.

Examples of creep:
A clothesline will stretch over time and will no longer be tense.

TIVAR Cestidur is a modified PE-UHMW with an extremely high molecular weight. This, in combination with a very specific manufacturing process, results in a PE-UHMW type with even better wear and abrasion resistance than the TIVAR 1000.

TIVAR Cestidur has proven itself as an excellent plain bearing and wear material in many industries and under harsh working conditions.

The main advantage of ECTFE is not only the good diffusion resistance or the wide usage temperature range, but especially the excellent chemical resistance. ECTFE can be used in the vicinity of a caustic soda or potash solution. In addition, ECTFE is highly resistant to oxidation acids with a high concentration such as sulfuric acid (> 97%) and nitric acid (100%) and chlorine compounds such as chlorine dioxide or sodium hypochlorite.

PTFE and FEP are similar in their material properties. The main difference between PTFE and FEP lies primarily in the maximum use temperature and the colour. PTFE is milky / white and FEP is clear transparent.

Material properties:

  • lower melting temperature than PTFE
  • more flexible than PTFE
  • clear transparent
  • low dielectric constant (insulating)
  • chemically inert

Polyethylene / Polythene (PE)

External identification: Feels greasy, low gloss, very dull sound, very light weight.

There are 3 types of PE: HD (High Density), HMPE (High Molecular Weight) and UHMPE (Ultra High Molecular Weight).

Fire test: Burns quickly and is not self-extinguishing.

Mechanical properties: PE is a fairly tough material, has excellent sliding properties and a high impact resistance even at low temperatures. It is also very wear-resistant.

The higher the molecular weight, the higher the impact and notch impact resistance, the wear resistance, the tensile strength and the toughness, and the better the resistance to high temperatures and chemicals.

As nothing adheres to the material, it cannot be glued.

Moisture & weather resistance: The UV resistance of PE is low, but the material has excellent electrical properties. Since it does not absorb moisture, it is very suitable for insulation purposes.

Properties & applications: PE is widely used in the food industry: cutting plates, guide rails.

The material has very good chemical properties, it is resistant to diluted acids, alkalis, many solvents (not benzene and trichlorethylene), alcohol, petrol, water, grease and oil. Hence why it is also widely used in the chemical industry, construction of installations and refrigeration engineering.

Standard available range: Sheet material in all colours, thicknesses and dimensions.

Some solvents cause swelling. It can constantly withstand temperatures up to 80°C and temperatures up to 95°C for a short time.

LDPE has more branching (about 2% of the carbon atoms) than HDPE. Due to its high degree of branching, LDPE is less crystalline, so its density is lower.

Polyamide, better known as nylon, is a high-quality plastic with a good wear-resistant effect. Moreover, polyamide (PA) is very strong, chemically resistant, electrically insulating and vibration absorbing.
