Thermoplastics and technical polymers for injection moulding

Below we provide a list of plastic materials that undergo injection moulding to create your items.
Click on them to learn about the technical features and scope of application.


Acrylonitrile butadiene styrene

Initially, it was considered a special type of polystyrene with higher impact strength. Its standard features are hardness, rigidity, good low temperature resistance, relatively high temperature resistance and easy metallisation. ABS is an excellent compromise between the above features and makes this resin suitable for all sectors.


Flexible polyvinyl chloride

Good resistance to chemical agents and corrosion, resistant to static loads and impacts, elastic also at low temperatures but with poor mechanical properties. Flexible PVC pieces have a glossy or translucent surface and are transparent (even if far less than PMMA and PC); they can be also coloured. Suitable for industrial use.


ECTFE – ETFE – PFA – PVDF – Carbon fibre filled fluorinated polymers

For high technology applications, thermo-processable fluoropolymers are the most synthetic plastic materials used and are in the top spots of the thermoplastic quality ranking..



Solvay IXEF® PARA, polyarylamide (semi-crystalline aromatic polyamide) is a thermoplastic product reinforced by glass fibres and/or mineral fillers .


Liquid crystal polymer

LCP stands for Liquid Crystal Polymer Due to its flame resistance, this material is widely used for airplane interiors. These crystal liquid polymers have great mechanical properties, chemical and thermal resistance, which make them a great alternative to metals, special polymers, and ceramics. It is also available with glass filler.
Benefits provided by LCP:

    • excellent creep resistance
    • impact strength and notched impact strength
    • intrinsically fire-proof
    • excellent chemical resistance
    • rigidity, dimensional stability, and low thermal expansion also at high temperatures
    • design freedom, to be used for complex pieces or thin walls
    • high dielectric strength.

It is also used for containers/sterilisable components for medical use, diagnostic imaging, sensors, and chip-holders in electronics, aerospace, telecommunications, optical fibres, and lighting applications.


PA6 – PA66 – PA46 – Glass fibre filled NYLON and MOS2

Nylon include all polyamide polymers. Nylon has a high water absorption power..



Transparent material, which can be provided with any colour gradient. It is widely used thanks to its multiple characteristics: great impact strength, low humidity absorption, surface hardness, non-toxic, good electrical properties, and excellent UV ray stability. It is usually applied in the automotive (for headlights, etc.), house appliance, and medical industries, as well as for safety and electric devices (sockets and plugs, etc.), lighting, and general consumer goods.


High-density polyethylene

PE-HD, high-density polyethylene (low pressure) has higher strength, density, hardness, and melting point compared to PE-LD. Also the chemical resistance at low and high temperatures is better, and it is also more resistant to UV rays, impacts, and wear.
Polyethylene is widely used thanks to the excellent value for money, especially in the food (containers, etc.), electronics, building, chemical, electricity, and automotive industries, etc.


Low density polyethylene

PE-LD or LDPE, low density polyethylene (low pressure) is a relatively soft material, strong, and resistant to moderate temperatures.
Polyethylene is widely used thanks to the excellent value for money, especially in the food (containers, etc.), electronics, building, chemical, electricity, and automotive industries, etc.


Linear low density polyethylene

Compared to LDPE, linear low density polyethylene is more resistant to impact and tear; it can be used for applications with reduced thickness but it is less transparent. It features good chemical resistance and good electric properties in addition to flexibility and tensile elongation. LLDPE is also used on a large scale in most of traditional polyethylene markets and it is suitable for food contact.


Poly(methyl methacrylate) / Polymethyl methacrylate

Excellent optical properties (92% of light transmission), unequalled deterioration resistance, dimensional stability, great resistance to sunrays and weather agents, and excellent electric properties. PMMA is the most transparent among plastic materials; moreover, it is odourless, tasteless, non-toxic, and can be moulded in multiple glossy and matt colours. It has a greater breaking point compared to glass and lower compared to polycarbonate; it can be considered the light alternative to glass. It is used for lamps, illuminated signs, toys, and in the food, cosmetic, medical, and furniture industries.


Carbon fibre filled PP – PP – Glass fibre filled PP

Its easy processing allows it to be used in a wide range of application, both as a homopolymer or copolymer..


PPS Polyphenylene sulphide and glass fibre filled PPS

PPS is an engineering plastic in which sulphur atoms bind aromatic elements between them.

POM and fillers

Polyoxymethylene/Acetal resin – POM molybdenum disulphide filled, carbon and glass fibre

It is a crystalline polymer with excellent friction and mechanical properties; it can be easily processed and it has high dimensional stability and humidity resistance. POM is used for small parts (cogs, bearings, dimensional stable precision pieces, guides, etc.), pump bodies, flanges, and, in general, for mechanical components subject to stress.

Adding MOS2 to acetal resin (POM+MOS2) improves the material’s crystalline structure, sliding properties, and it makes it more elastic and oil resistant. Due to its self-lubrication properties, molybdenum disulphide increases wear resistance.
In addition to MOS2 filler, Crea moulds carbon and glass fibre filled POM upon request.


Polyphenylene oxide / Polyphenylene oxide

PPO is a self-extinguishing material with excellent dimensional stability and rigidity properties, low water absorption, resistant to hot water and vapour and poor thermal expansion. It also features excellent electrical properties (it is a good insulator), it allows for easy mechanical processing of pieces, low specific weight, and good ageing resistance. PPO is opaque and, due to the characteristics above, it is used for engineering pieces, pump impellers, electric items, sanitary products, joints, sterilisation-resistant items, solar panels, computers, and as an alternative to metals.

We at Crea mould also glass-filled PPO.


Extruded polystyrene / Polystyrene

Thermoplastic aromatic polymer belonging to the styrene resin family. Polystyrene is transparent, hard, rigid, and affordable with fairly good mechanical properties and, at the same time, it is fragile. Due to the latter characteristic, it is usually used with the addition of impact-resistant components to make it more resistant. It can be easily coloured and it is used for various applications, especially in the household and toys industries.


PES Polyethersulphone – PSU Polysulphone

Sulphonated polymers are high performance aromatic thermoplastic and transparent resins featuring sulphone



Thermoplastic elastomers have the typical benefits of rubber, in terms of elasticity, and the same features as plastic materials..


PEEK polyetheretherketone - carbon and glass fibre filled PEEK, PTFE and graphite

Peek is one of the world’s highest performing thermoplastic polymers..
