Materials

Flexible Materials:

PVC (Polyvinyl Chloride)

The most commonly employed flexible thermoplastic compound used for its versatility. Used on its own or as the flexible element of a co-extrusion. As with rigid PVC, it is compounded in clear and coloured grades and in a UV stabilised form. Available over a wide shore hardness range.

PVC/NBR (PVC Nitrile)

An enhanced PVC grade offering improved oil resistance and a wider temperature range.

Tpe (Thermoplastic Elastomer)

An equivalent to synthetic rubbers such as EPDM, this material has the advantage of being recyclable and non-marking. Sometimes replaces flexible PVC. Grades are SBS or SEBS based and are co-extrudable to rigid plastics such as ABS, PP and PS. Clear and opaque versions are available all offering good compression recovery. Specific glazing grades for UV resistance and weatherability as well as compatibility with non-glass glazing media.

Tpe - MPR

A melt-processable rubber with specific properties, it permits co-extrusion to uPVC and ABS. Good compression recovery.

Tpe - Vinyl-based

Developed to perform as a Tpe and be co-extrudable to PVC it is eminently suitable for glazing applications with excellent outdoor performance and compatibility with PC and other non-glass glazing media. Black and white grades.

Tpe (Thermoplastic vulcanizate, aka Santoprene ®)

A unique blend of a Tpe with some EPDM rubber, this is a high-performance material. With superior fatigue resistance and high tear strength it also offers a constant service temperature range of - 60° to + 135°. Used in medical and food applications with USP Class VI grades.

POP (Polyolefin plastomer)

Tough, high clarity food grade polymer which is highly flexible and elastic.

Tee (Thermoplastic polyester co-polymer)

With an extended performance life, this engineering thermoplastic has a high modulus and is especially suited as a hinge material in co-extruded applications.



The above list is intended only as a guide to polymers we currently process. New and modified grades are constantly being reviewed and introduced.

Rigid Materials:

uPVC (unplasticised, or rigid, Polyvinyl Chloride)

The commodity thermoplastic most widely used across all industries. Durable, stiff and with excellent chemical resistence it is highly versatile with grades suitable for both indoors and outdoors as well as food grades. Inherently fire resistant being self-extinguishing, it is compounded in clear and coloured versions.

uPVC re-work/re-chip

Re-processed material can be extruded again without loss of performance when function and price outweigh aesthetics. Especially welcomed where sustainability is required.

ABS (Acrylonitrile Butadiene Stytrene)

Tough and opaque with good impact and chemical resistance. Offering a wider working temperature range than PVC, especially lower down the scale. Better employed indoors but accepts paint/adhesives.

HIPS (High impact Polystyrene)

Lower density, rigid, brittle. Available in clear and coloured grades. Indoor use, accepts painting, plating and adhesives.

PA (Polyamide) (aka Nylon)

Tough, rigid, translucent and hard wearing. Resistant to fuels, oils, fats. A little susceptible to moisture absorption but has good creep resistance.

PC (Polycarbonate)

Outstanding impact resistance. High dielectric strength, good high temperature performance and offering good flame resistance. Clear. Opaque grades available.

PC/ABS Alloy

Better chemical resistance than PC with higher temperature and flame performance than ABS

PE (Polyethylene)

Processed in both low (LDPE) and high (HDPE) versions, this is a tough and translucent polymer with a low co-efficient of friction. Good chemical resistance, used indoors and outdoors.

PETg (Polyethylene Terephthalate co-polymer)

Touch and creep resistant, offering excellent clarity. Suitable for food use.

POM (Polyoxymethylene or Acetal)

Most often specified as a moulding grade, this is a rigid and touch polymer with excellent resistance to wear, creep and stress relaxation.

PP (Polypropylene)

Highly inert semi-rigid material in co- and homo-polymer derivatives. Tough and offering good chemical resistance as well as low friction.

PPE/PPO (Polyphenylene Ether/Polyphenylene Oxide)

Opaque, engineering grade materials with good dielectric strength and heat distortion temperature. Some grades low smoke/halogen free.

SBC (Styrene Butadiene copolymer)

Clearer and lighter than PVC and offering good impact and UV resistance.

WPC (Wood/plastic composite)

A polymer containing wood flour. Lightweight and durable, it is used to give a wood effect to the profile.
