PS/HIPS

Polystyrene is a highly used commodity plastic and is ranked fourth in global production volume after PE, PP, and PVC.

HIPS is a high-impact resistant polystyrene, which has been modified by rubber.

Characteristic features:

Hard amorphous polystyrene is crystal-clear, hard, brittle, and sensitive to impact.  It generates a rattling, glass-like sound when struck.  Polystyrene may be dyed to match any color choice.  In foamed form, it has a white opaque color and, in comparison to solid polystyrene, lower mechanical strength but higher flexibility.

HIPS is usually not transparent due to butadiene content, but it is more impact and cold resistant.

Applications:

PS is used for packaging (e.g. foils, yoghurt cups, cases), disposable cutlery, switches, and coil bodies.

HIPS is mainly used in the consumer electronics sector for televisions, phones, and PC-housing units. Thermoforming is used to produce the inner linings of refrigerators with HIPS.

ASA

Acrylonitrile styrene acrylic ester (ASA) is an impact-resistant terpolymer. It has similar properties to ABS, but is more weather resistant.

If required, suitable additives for the respective application are incorporated into the plastic matrix. UV stabilizers, antioxidants, and lubricants are to be mentioned here.

Characteristic features:

ASA produces high-quality, glossy, scratch-resistant surfaces, we well as transparent surfaces if required.  Through the use of matting agents or larger acrylic phases, matt surfaces are also possible.

ASA has an excellent chemical resistance due to the high polarity of acrylic components, especially when compared to polybutadiene components found within ABS.  The material demonstrates high resistance towards aqueous mediums, including diluted acids & alkalis, detergents & oils/fats, alcohols, and aliphatic hydrocarbons.

Applications:

ASA is often used for weather-resistant building components, as well as for electrical appliances that require a high temperature resistance.  This material demonstrates long-term durability when used for sport and recreational applications, as well as for exterior automobile parts.

SAN

Styrene acrylonitrile (SAN) is a copolymer made from styrene and acrylonitrile. SAN has properties similar to polystyrene and is transparent and relatively stiff. A typical composition consists of 70% styrene and 30% acrylonitrile.  SAN has higher strength, thermal resistance, chemical resistance, and scratch resistance in comparison with polystyrene.

Characteristic features:

Transparent and translucent

Good chemical resistance

Scratch resistant

Thermal resistant

Relatively low water absorption

Applications:

Glazing for industrial doors, sectional doors & shower cubicles

Kitchen supplies (salad bowls & cutlery, measuring cups, parts for kitchen machines)

Refrigerator inserts

Compounding

ABS

Acrylonitrile-Butadiene-Styrene (ABS), as an amorphous thermoplastic is a synthetic terpolymer (terpolymers are copolymers made out of three monomers, being statistically distributed in the linear macromolecule) from the monomers of acrylonitrile, butadiene, and styrol.

Large scale production of ABS can be done by graft polymerization, as well as through the blending of the polymers.

Characteristic features:

Good chemical resistance

Good mechanical and acoustical noise absorption behavior

High impact and notched impact strength

Easy coloring process for all types of color

Metal plating and galvanizing

Low water absorption

Applications:

Toys, household goods industry, automotive, sanitary applications, compounding.

PE 80/100

Polyethylene (HD-PE) is a competitively priced thermoplastic that is characterized by good UV resistance, physiological safety, and good chemical resistance. The material is easily recycled due to its simple molecular structure.

PE is classified in strength classes according to ISO 9080 (PE 80, PE 100) in plastic pipe construction. PE 100 materials are produced by a modified polymerization process (bimodal Hostalen Process), through which a modified molecular mass distribution is demonstrated. This achieves higher density and also improves mechanical properties, such as increased stiffness and hardness. All pipes that may be used for drinking water are tested and categorized according to ISO 4427 and EN 12201.  We also offer chlorine-resistant materials that prevent oxidative degradation, which lengthens the service life of the finished products.

Characteristic features:

Physiologically harmless (suitable for drinking water), weather & UV resistant, temperature resistant from -40°C to +50°C, good chemical resistance, very good abrasion resistance,  leak-free & flexible pipe connections due to good weldability.

Applications:

Gas & water supply, sanitation, cooling & service lines, production lines, and industrial pipelines.

UHMWPE

Ultra-High-Molecular-Weight Polyethylene

UHMWPE are PE types with molecular weights ranging between 1 million g/mol to 10 million g/mol. Standard types are used in the range of 3-5 million g/mol. As the molecular weight increases, wear resistance and impact resistance improve.

PE-UHMW shows the most balanced qualities of all polyethylenes and offers a very good impact resistance even at temperatures as low as negative 200°C.

Characteristic Features:

Best wear resistance of all technical plastics at room temperature, very low friction coefficients,

best sliding properties, very good tension crack resistance, noise reduction, UV resistance.

Applications:

Protective devices, lining technology, general mechanical engineering, conveyor technology, medical technology, protective clothing, sports & leisure supplies.

Processing:

Due to the high molecular weight, the material viscosity also increases, so that PE-UHMW can usually only be processed by either RAM extrusion or pressure sintering. As a result, semi-finished products can be further processed with very low-stress. We are currently working together with our partner, IRPC, to develop a UHMWPE granulate type suitable for injection molding.

TPEE

Thermoplastic polyetherester elastomer (TPEE) is a linear block co-polymer made out of dicarboxylic acid derivatives,  long-chain diols (molecular weight, 600 to 6000), and a mixture of diols with low-molecular weight.  TPEE is produced through a melting transesterification process.

Characteristic features:

TPEE has all the properties of vulcanized rubber grades, especially compression resistance at room temperature and lower temperatures.  When compared to rubber, it is easier to process and has a longer service life. TPEE has a wide hardness range, high structural performance, flexibility, impact resistance, easy processability, good melt flowability, melt state stability, low shrinkage, and quick crystallization.

Applications:

TPEE is ideal for parts and fibers that need excellent bending fatigue properties and a large operational temperature range. It has high cut & tear propagation, creep strain, and friction resistance.

POK

Polyketone (POK) is a semi-crystalline, high-performance thermoplastic polymer. The polar ketone groups create a strong attraction between polymer chains, resulting in a high melting point and outstanding technical properties. POK closes the technological gap between POM and PA66.

POK is formaldehyde-free and environmentally friendly due to the binding of CO molecules in the polymer.

Compared to all other semi-crystalline polymers, POK has by far the highest elasticity (elongation according to ISO 527-1: over 300 % regardless of humidity).

POK is available in various injection molding grades, as well as in extrusion grades (e.g. for semi-finished products with subsequent machining).

Characteristic features:

High elongation, outstanding tribological properties, good chemical resistance, good barrier properties.

Applications:

Gears, pipes, pipe connectors, semi-finished products, parts that must have high friction resistance or excellent barrier properties.

We have the necessary approvals for many fields of applications (FDA, EU 10/2011, WRAS, NSF61, W270, EN71, etc.).
