Perforated Rubber / Plastic
Think Perforatation – Think Graepels
What is perforated rubber and where is it used?
Perforated rubber is a versatile and high-performance material that is used for processing industries. such as quarrying and recycling. ubber mats and screens are used for static and mobile plants during demolition screening.
Rubber is also used for screening in the Agricultural and Food Processing industries, for example in screening mats for potatoes. Graepels perforate for a range of sectors.

Graepels high performing, quality Perforated Rubber is available in 3 main material types:
- Polyurethane & Vulkolan: Also referred to as Spaleck, Bivtec and Binder which are the brand names for this material are perforated by Graepels to suit all makes of machinery.
- EPDM: SAR Grade Rubber with a shore hardness of 65 to avoid abrasion -widely used for the mineral processing industry. Specifically designed to display excellent resistance to impact abrasion to DIN22102. Our rubber screens are reinforced with a special heat-treated polyester cord which is resistant to deformation during operation, enabling tension while in service without the need for adjustment. Rubber screen cloth has superior noise reduction qualities over metal screens, providing a better/safer working environment for your personnel.
- Alternative shore hardnesses are available to suit your requirements.
Our Machinery offers an impressive cutting force of 40 tons and cutting strokes of 110mm. For alternative material enquiries please contact our team directly.

Flip flow, Polyurethane Screens tend to be lighter, thinner and more flexible than Rubber Screens and can be successfully punched in different hole shapes with smaller apertures. Polyurethane screens work best where plugging is an issue.
Advantages of Flip Flow Screens
- Screens are noise reducing, creating an improved working environment for personnel
- Aperture size of 4mm to approx 50mm
- Compact and well designed construction
- Wear resistant -They do not suffer from pitting or stress corrosion, particularly in the presence of seawater
- Screens can be manufactured by Graepels to suit almost all makes of machinery within the quarrying, waste management and recycling industries
- Low operating and maintenance costs
Graepels Rubber screens can be adapted to suit almost all makes of machinery. Rubber screens offer many advantages including longer life span and reduced noise levels. They are particularly suited to the upper part of screen decks, or on a complete deck, where required.
Advantages of EDPM Rubber Screens
- Screens are noise reducing, creating an improved working environment for personnel
- Rubber screens are manufactured in natural SAR Grade rubber with a shore hardness of 65, which offers excellent resistance to impact abrasion
- Screens can be manufactured by Graepels to suit almost all makes of machinery within the quarrying, waste management and recycling industries
- They do not suffer from pitting or stress corrosion, particularly in the presence of sea water.

- Durable, long lasting compared to wire depending on the material being screened
- Light (depending on material and thickness this can change) lighter panels and components are easier to work with/handle and reduce transportation fuel and costs.
- Reduce noise level for screening
- Noncorrosive in wet conditions
- Cost effective
- Punch rapidly – available stock or to suit specific customer specification
- Polyurethane screens, also known as flip flow mats, tend to be lighter, thinner, and more flexible the rubber screens. These work well where plugging is an issue.
