TPE-SEBS

 

Flexochem SEN is a TPE thermoplastic elastomer (also referred to as TR thermoplastic rubber) formed in the process of mixing of hard thermoplastics (e.g. polypropylene, polystyrene) with a soft SEBS rubber (styrene-ethylene-butylene-styrene copolymer).

Due to the saturated nature of SEBS rubber, Flexochem SEN has excellent resistance to weather conditions, UV and ozone. Our compound retains its properties in a wide temperature range from -50°C to 120°C. The material combines the advantages of thermoplastics, such as the ease of processing and recycling, with the advantages of rubbers, such as flexibility, shape memory and softness.

Characteristic:

  • excellent resistance to weather conditions, UV and ozone
  • resistance to chemicals
  • hardness range from 30 ShA up to 50 ShD
  • operating temperature from -50°C up to 120°C
  • density from 0.89 up to 1.25 g/cm3
  • high fatigue resistance
  • perfect shape memory
  • good abrasion resistance
  • rheological properties adapted to the customer's requirements
  • wastes can be recycled repeatedly (without significant loss of properties)

Examples of applications:

  • handles
  • seals and straight as well as co-extruded profiles
  • soft covers
  • sealing tapes
  • roofing membranes
  • anti-slip mats
  • anti-vibration pads
  • elements of footwear
  • sport equipment
  • elements of home appliances and electronics
  • toys
  • styrene plastics impact modifier

SEN Flexochem can be processed by injection moulding, extrusion and co-extrusion. Each grade of elastomer, its properties and processing temperatures are adapted to the customer’s individual requirements.

 

TPE-SBS

Flexochem SN is a thermoplastic elastomer (TPE) (also referred to as TR thermoplastic rubber) formed by combining the SBS elastomer phase (styrene-butadiene-styrene copolymer) with a thermoplastic phase, usually polyolefins or styrene polymers.

Thanks to the use of the thermoplastic phase, Flexochem SN is easily processable, susceptible to dyeing and can be 100% recycled. The elastomeric phase provides very good mechanical properties even at low temperatures (-50°C).

Due to the unsaturated nature of rubber, SBS Flexsochem SN is not resistant to UV radiation, therefore it is better adapted for internal applications, while its resistance can be increased by using appropriate additives.

Characteristic:

  • hardness range: from 30 ShA up to 40 ShD
  • operating temperature: from -50°C up to +60°C
  • density: from 0.89 up to 1.25 g/cm3
  • good abrasion resistance
  • rheological properties adapted to the customer's requirements
  • possibility of dyeing to any colour
  • wastes can be recycled repeatedly (without significant loss of properties)

Examples of applications:

  • handles
  • seals
  • sealing tapes
  • anti-slip mats
  • footwear
  • elements of home appliances and electronics
  • toys
  • sport equipment
  • styrene plastics impact modifier

SEN Flexochem can be processed by injection moulding, extrusion and co-extrusion. Each grade of elastomer, its properties and processing temperatures are adapted to the customer’s individual requirements.
