Plastic Stock Shapes

Acetal Copolymer (OmniAcetal)

Overview

Polyoxymethylene, commonly called Acetal, is a crystalline polymer obtained from the polymerisation of formaldehyde. Discovered fairly recently (1960), it has enjoyed rapid growth and large acceptance thanks to its excellent mechanical features, stability to humidity and ease of machining. All our stock shapes made of POM are marked along the whole length with product code and batch number, according to ISO 9002 standards.

Acetal Homopolymer (Delrin)

Overview

The general features of the homopolymer Acetal resin are similar to those of the copolymer POM-C. However, the service temperature (under load) is slightly higher but the resistance to hydrolysisis and strong alkalis is slightly lower. POM-H is more commonly known as Delrin®. POM-H has a slightly higher mechanical strength than the POM-C but both are easy to machine and offer excellent dimensional stability.

PET-P (Arnite & OmniaLite)

Overview

Arnite is a relatively new semi-crystalline polymer developed for technical applications. It is suitable for mechanical parts which require dimensional stability and a low friction coefficient. Omnialite is a modified PET designed to provide a higher shock resistance than Arnite by reducing the E-modulus.

Cast Nylon PA6G (OmniaMid)

Overview

Cast Nylon 6. The method of production of this polyamide (i.e. the polymerisation of the caprolactam directly in the mould) allows the production of stock shapes in larger than normal dimensions, such as big rings or very thick sheets. The general features are similar to those of Nylon 66.6, which means that it is stiffer and more brittle than extruded Nylon.

Full details

Nylon 6 (Akulon 6) Extruded

Overview

Semi-crystalline polymer Nylon has goods general features and excellent quality/price rate. Using only high viscosity raw material for the extrusion of our Nylon 6 stock shapes grants a very high quality level: mechanical resistances as well as sliding properties are higher if compared with other low viscosity Nylons. Our unique annealing process grants dimensional stability and easy machining.

Full details

Nylon 66 (Akuon66) Extruded

Overview

Polyamide obtained by the polymerisation of Hexamethylenediamine and Adipic acid. It is one of the oldest engineering plastics, having been created in the USA in 1930. Due to its origin it is widely used in the American and English markets. In comparison to PA6 it is more stiff and tougher but is also more brittle. It is advisable to use PA66 instead of Polyamide 6 when a higher stiffness is required to the detriment of resilience. It can be easily machined on automatic machine tools.

Full details

Nylon 66.6

Overview

Copolymer of nylon with excellent mechanical features, it combines the good impact resistances of PA6 as well as the higher stiffness of PA66. For this reason it machines very well on automatic tools and on CNC centres. The U.V. stabilisation makes it light resistant and it is therefore suitable for outdoor applications.

Full details

Nylon 12

Overview

The only engineering plastic of natural origin (derived from castor oil), it is a polyamide which, unlike the other nylons, does not absorb humidity. It has all the good mechanical features of polyamides: tensile stress, compressive strength, wear resistance, etc. Moisture content does not influence its shock resistance. It has very good ageing and low temperature resistance.

Polyethylene: PE300, PE500, PE1000

Overview

High Density Polyethylene (HD-PE300) has excellent impact strength, even at temperatures as low as -30ºC. Coupled with low coefficient of friction and ease of fabrication, HD-PE300 is widely used in automotive, leisure and industrial applications and is particularly suitable for the fabrication of tanks, silos, hoppers etc. HD-PE300 can also be supplied to colour matched, talc-filed and conductive forms.

Full details

Polypropylene

Overview

Polypropylene provides excellent resistance to organic solvents, degreasing agents and electrolytic attack. It has a lower impact strength, but its working temperatures and tensile strength are superior to low or high density polyethylene. It is lightweight, resistant to staining, and has a low moisture absorption rate. This is a tough, heat-resistant, semi-rigid material, ideal for the transfer of hot liquids or gases. It’s recommended for vacuum systems, where higher heats and pressures are encountered.

PVC (U-PVC)

Overview

PVC has high hardness, good mechanical properties, high tensile strength and excellent chemical resistance. It is self-extinguishing and has class 1 fire rating. This is vital for construction applications and making flat sheet PVC ideal for wall cladding applications and hygienic-cladding. It has good electrical properties in the low voltage and frequency range. This tough plastic can be easily fabricated, welded and bonded together with solvent cements making it one of the most versatile plastics available.

PTFE (Teflon)

Overview

This product is more commonly known by the brand name Teflon® and is renowned for the lowest friction coefficient. It also has exceptional chemical resistance and dielectric properties. Despite excelling with the above properties it has poor mechanical properties, which is why is can be modified with both glass and carbon to improve the dimensional stability.

Full details

PEEK

Overview

Peek has excellent mechanical strength, dimensional stability, a low coefficient of friction, very good chemical, hydrolysis resistance and radiation resistance, good dielectric properties and a low notch impact strength. UL94 Vo rated (self-extinguishing). Temperature range -50°C to +250°C.

Full details

PVDF

Overview

PVDF is a relatively new fluoropolymer. Like the other fluoropolymers, its best feature is its chemical resistance. The mechanical features of PVDF are notably higher than PTFE and it does not suffer strain under load.

Full details

Phenolic Cotton Laminates

Overview

This material is made by applying heat and pressure to layers of Super Fine Weave Cotton and synthetic resin. When heat and pressure are applied to the layers a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic

Full details

Acrylic Cast

Overview

Acrylic is polymethyl methacrylate (PMMA), which is sold under the brand names of Plexiglas, Lucite, Perspex, and Crystallite. PMMA is a tough, highly transparent material with excellent resistance to ultraviolet radiation and weathering. It can be coloured, moulded, cut, drilled, and formed.

Full details

Polycarbonate

Overview

Polycarbonate material is formed by a condensation polymerization resulting in a carbon that is bonded to three oxygen atoms. It’s a transparent, strong and stiff thermoplastic material with outstanding impact resistance.

Full details

ABS

Overview

Acrylonitrile Butadiene Styrene (ABS) is the polymerization of Acrylonitrile, Butadiene, and Styrene monomers. Chemically, this thermoplastic family of plastics is called “thermopolymers”, in that they involve the combination of three different monomers to form a single material that draws from the properties of all three. ABS can be used in temperatures ranging from -50°C to +70°C

Full details

Noryl

Overview

The NORYL family of modified PPE resins consists of amorphous blends of PPO™ resin (polyphenylene ether) and polystyrene. They combine the inherent benefits of PPO resin (affordable high heat resistance, good electrical properties, excellent hydrolytic stability and the ability to use non-halogen FR packages), with excellent dimensional stability, good processibility and low specific gravity. NORYL resins offer a good balance of mechanical and chemical properties, and may be suitable for a wide variety of applications.

Polysulphone PSU

Overview

PSU is a semi-crystalline polymer. It’s a material with high mechanical and thermal properties (up to 240°C.). It resists to creep under load and to wear, its friction coefficient is low. The temperature resistance without load is high but it is reduced by the addition of load even if limited.
