Bonaprene Products are specialists in the manufacture of a 
wide range of engineering plastic (thermoplastic) parts.
Modern machine tools and inspection systems ensure 
competitive prices with high quality.

Bonaprene Products' expert knowledge and experience of 
plastic materials and plastic materials' applications enables 
Bonaprene to advise customers as to the most suitable material 
for their product. This often includes less expensive alternatives.

Today's plastics are now out-performing the more traditional 
materials in areas that would not have been considered a few years 
ago. Bonaprene Products are able to advise customers on money saving 
alternatives. This can be verified with trials and test data.

Bonaprene Products work with all the main thermoplastic groups 
including polyamide (Nylon), polyethylene, polypropylene, 
polycarbonate, acrylic, polytetrafluroethylene (PTFE), 
Polyvinylchloride (PVC) and Acetal.

Precision Machining

Bonaprene Products operate a comprehensive machine shop for manufacturing
precision engineered plastic parts. Bonaprene Products turn, mill, drill
and grind plastic stock shapes on CNC and standard equipment to customers' 
drawings. Quantities can vary from one of prototypes to large production batch sizes.
Bonaprene Products can produce parts from 3D CAD models and 
2D drawing files as well as printed paper drawings.

CNC Routing

Bonaprene Products operate CNC routers linked to computer design software.
The CNC routing machines have a capacity of 2.44 meters x 1.22m x 70mm 
(8' x 4' x 2¾"). This equipment allows Bonaprene Products to manufacture
a huge range of plastic parts from one of prototypes to large production 
batch sizes. Bonaprene Products can produce parts from 3D CAD models and 
2D drawing files as well as printed paper drawings.

Fabrication

Bonaprene Products offer a comprehensive plastic fabrication service. Bonaprene
Products operate a 2.0 meters x 25MM (6'6" x 1") hot wire bender and all the
necessary welding facilities. Bonaprene Products can weld in polypropylene
co-polymer and polypropylene homo-polymer; polyethylene 300 grade; polycarbonate
and acrylic. Bonaprene Products can glue fabricate in polycarbonate
and acrylic.

500 Grade Polyethylene (PE) 
This grade of polyethylene has a good combination of stiffness, toughness, mechanical 
damping ability with abrasion resistance. It is suitable for the less demanding 
applications with respect to wear and impact resistance and makes an economical 
alternative for 1000 grade. PE 500 is versatile and used widely in the food processing 
industry For 500 Grade Polyethylene click here
 
1000 Grade Re-Generated Polyethylene (PE) 
This grade of polyethylene is composed of re-processed PE-UHMW material. It has 
overall lower property level than the virgin PE, although with still good mechanical 
properties and a lower cost than virgin 1000 grade. Not suitable for food applications. 
Much better impact strength and wear resistance when compared with PE 500.

1000 Grade Virgin Polyethylene (PE) 

1000 grade polyethylene exhibits a very well balanced property profile. It combines a 
very good wear and abrasion resistance with an outstanding impact strength.

Nylon 6 – Polyamide

Nylon 6 is a partially crystalline polyamide with good strength, toughness and 
resilience. This is particularly important under impact load or at low temperatures. 
It is available in a wide range of extruded stock shapes, rod, tube, sheet and plate.

Nylon 66 – Polyamide

In comparison with Nylon 6, Nylon 66 has a higher melting point, better mechanical 
properties and greater hardness. Because of its lower water absorption it is more 
suited for components that have to meet closer tolerances. It is available in a wide 
range of extruded stock shapes, rod, tube, sheet and plate.

Nylon 66 – MoS2 filled – Polyamide

The performance of nylon 66 can be enhanced by the incorporation of a filler. Nylon 66 
has been modified with molybdenum disulphide (MoS2), which results in a material with 
ven better wear resistance and a lower coefficient of friction. Stiffness, tensile 
strength and temperature resistance are also improved. It is ideal for dynamic bearings 
and wear applications.

Nylon 66 + 30% Glass Filled – Polyamide

Compared to unreinforced nylon 66 this 30% glass filled grade offers increased strength 
and stiffness with much better creep resistance and dimensional stability. It also offers 
a higher continuous service temperature of 120 ºC. The overall combination of properties 
makes it ideal for static structural applications.

PTFE – Unfilled 
Unfilled polytetrafluoroethylene (PTFE) is the most widely used of all the fluoropolymers.
It has a unique combination of properties; outstanding chemical resistance, very low 
coefficient of friction, superb electrical insulating properties, a wide working 
temperature range (-260 ºC to + 260ºC), low flammability and high resistance to weathering.

PEEK – Unfilled 

Unfilled polyetheretherketone (PEEK) is a unique, high performance engineering plastic 
developed by ICI Advanced Materials. It is also tough rigid and strong with a very good 
chemical and radiation resistance. PEEK has an estimated continuous working temperature 
of 250°C with useful mechanical properties being retained even at 300°C. PEEK can be 
used for thousands of hours at high temperature in steam or high pressure water 
environments with no significant degradation of properties. Radiation resistance is 
also exceptional for a plastic material; it can absorb over 1000 Mrads of radiation 
with no appreciable loss of mechanical properties. PEEK has inherent UL 94 V-O 
flammability rating down to 1.45mm without the use of additives. During combustion 
the levels of smoke and toxic acid gas released are among the lowest of any 
thermoplastic. Peek is insoluble in all common solvents and, being crystalline, has 
excellent resistance to a wide range of organic and inorganic liquids even at 
elevated temperatures.
