ORA Squeegees can produce many different Polyurethane blends, offering Squeegees with hardness ranging from 45 Shore A to 95 Shore A.
All materials are stored, prepared and processed as per our supplier’s recommendations and cast through sophisticated, computer-controlled dispensing equipment, which ensures the end component has the maximum properties to suit our customers’ requirements.
Due to the breadth and depth of industries and markets that we serve, combined with the close inter-working relationship of our product groups, we are continually learning to supply better products, at better prices and with better service.
ORA Squeegees offer four distinct squeegee materials to cover the full spectrum of screen printing applications:
Lumina is a premium ORA Squeegee product offering market leading performance at competitive prices. This material delivers high abrasion resistance, impressive chemical resistance and very good all round properties. Suitable for use in a wide range of Screen Printing applications and ideal for a distributor selling into a variety of customers.
Ultima is an extremely good value range of ORA Squeegee blades, offering the same high quality as all ORA Squeegee Blades, with good performance across the range of products. Most commonly used for textile printing but is popular across a broad spectrum of Screen Printing applications.
The Maxima or MSR material has been designed to provide a solution to more extreme applications. Maxima is at the forefront of our ongoing development programme, which results in innovative and practical solutions to the problems created at the boundaries of screen printing development. It offers extremely high chemical and solvent resistance to enable longer life and quality of print, when other products fail. Also known as MSR (due to its Maximum Solvent Resistance).
Tetra is the ORA Squeegee material range offering the very highest abrasion resistance. Made from a Vulkollan® material, these squeegees will offer long life solutions in very tough applications. Vulkollan® is made under licence from Bayer AG and we are one of a small number of Global companies with the licence to produce this material.
The NEW G30Rotary Profiled ORA Squeegee Blade is a flexible blade constructed with a fibreglass backing and a Polyurethane Printing strip, offering optimum performance in rotary applications. The Polyurethane component is the ORA Tetra Series material, which is a Vulkollan ® polyurethane made under licence from Bayer AG.
The edges of ORA Blades are regarded amongst the best in the industry, using CNC Cutting Technology for a precise Linear Cut. The profiled items are also cut using a linear technique, ensuring the perfect finish to enable high quality print.
We work closely with suppliers to specifically formulate Polyurethane Materials to enable to highest performance in specific applications.
What is Polyurethane?
Polyurethanes are a general term that is used for a wide range of polymers but they are specifically high molecular weight polymers which are based on Isocyanate chemistry. All Urethanes are produced with a reaction between 3 components:
- A Polyol (PPG, PTMEG and Polyester)
- An Isocyanate (TDI, MDI, NDI)
- A cross-linker / Chain extender (Diamine, Diol and Triols)
In General the Polyol and Isocyanate parts are preblended liquids called Pre-polymers. This is then hand or machine blended with the cross linker, poured into a mould and cured to produce the end component.
There are many different families of polyurethanes, for example; Castable Elastomers, Rigid and Flexible foam, Adhesives, Sealants & Coatings.
We specialise in manufacturing castable Polyurethane products, which are true engineering materials. Castable Polyurethanes are true elastomers, the definition of which is a material that can be extended to at least twice its length and then return to its original form.
The major characteristic of these Polyurethanes are their extraordinary physical properties and the variety of strengths that are available between the different families of urethanes. There are two main reasons for using polyurethanes; their physical performance and their cost effectiveness.
ORA Squeegees produce Squeegee Blades using MDI and NDI polyurethane technology. Other products are also available using Tdi technology.
