Weprofab EDPM Sheet for Different Purposes
Waterproofing MembraneEPDM sheets are often used as waterproof layers for roofs, basements, and bridges because of their UV resistance, ozone resistance, and compact structure.
Sealing and Sound InsulationEPDM sheets are often used for sealing doors, windows, car doors, pipes, and curtain walls because of their wide temperature resistance, acid and alkali resistance, high elasticity, and compact structure. They have both waterproof and sound insulation functions.
Shock-absorbing ComponentsEPDM sheets are often used in various cushions and shock absorbers because of their excellent elasticity, and can absorb vibrations and extend the life of parts.
Insulating MaterialsEPDM sheets are often used in insulating sheaths of cables and protective parts of electrical equipment because of their excellent insulation.
Medical EquipmentSome EPDM sheets are biocompatible and can be used for medical catheters and respiratory masks.
Food Grade ApplicationsSome EPDM sheets have food grade certification and can be safely contacted with food, so they can be used in food processing equipment and conveyor belts.
Outdoor EquipmentEPDM sheets are often used in outdoor cushions, shock-absorbing layers of sports equipment, and edge seals of solar panels to prevent rainwater penetration due to their UV and oxidation resistance.
Railway TransportationEPDM sheets are often used in high-speed rail or subway door seals and rail shock-absorbing pads due to their excellent elasticity and wide temperature resistance.
Excellent Properties of Weprofab EDPM Sheet
EPDM sheets are resistant to UV, ozone, and oxidation and are suitable for outdoor environments.
EPDM sheets can adapt to a wide range of temperatures from -50°C to +150°C, and their flexibility is completely unaffected even in high and low temperature environments.
EPDM sheets have good resistance to weak acids, weak bases, saline solutions, and polar solvents, but are easily dissolved by hydrocarbons, oils, and aromatic compounds.
EPDM sheets have high tensile strength and remain unchanged under great pressure. They have good elasticity and can withstand severe impact.
EPDM sheets can maintain their structural integrity even under frequent friction and are not prone to rapid wear.
The closed-cell EPDM sheets have a tight structure that can resist moisture penetration.
EPDM sheets have excellent electrical insulation and can prevent electrical equipment from leaking electricity.
Some EPDM sheets comply with NSF-61 and FDA food grade certification and can be used in food contact scenarios.

How to Produce EPDM Sheet?
The production of EPDM sheet requires the following steps.
Step 1: You need to use EPDM as the main material, with 10-30% calcium carbonate filler and 2- 5 phr peroxide curing agent, and then use a high-speed mixer to premix the EPDM particles with 30% white oil plasticizer for 15 minutes, and the temperature needs to be controlled at 60-80℃.
Step 2: You need to use a two-stage mixing method. In the first stage, carbon black, zinc oxide, and other reinforcing agents are mixed in the internal mixer. The mixing time is 3-5 minutes, and the temperature is controlled at 110-130℃ to generate the mixed rubber. In the second stage, vulcanization accelerators and antioxidants are added, and the mixing time is 2-3 minutes to avoid scorching.
Step 3: You need to use a twin-screw extruder to control the barrel temperature in sections, with a feeding section of 80℃, a plasticizing section of 120℃, a homogenizing section of 150℃, and a three-roll calender to form at 70℃.
Step 4: You need to preheat the formed EPDM sheet to 160℃ through a microwave device, and then put it into a hot air vulcanization box for 5-8 minutes to achieve a crosslinking degree of ≥85%.
Step 5: You need to use a laser thickness gauge to monitor the thickness fluctuation of the EPDM sheet in real time, and use an automatic trimmer to control the sheet width tolerance within ±1mm.
Step 6: You need to perform key performance tests on the EPDM sheet. Including tensile strength test, UV resistance test, compression permanent deformation test, etc.
First, you need to assess the damage of the damaged EPDM sheets, use EPDM-specific cleaners to remove contaminants, and grind the carbonized layer until the fresh rubber layer is exposed. If the damage is small, you can use an uncured EPDM patch to apply the chloroprene rubber base glue, let it stand for 10 minutes until it is semi-dry, and then use a rubber roller to roll from the center to the edge to remove bubbles to complete the repair. If the joint is cracked, you need to inject polyurethane sealant, reinforce it with glass fiber mesh cloth, and cure it for 24 hours to repair it.
You can use a low-temperature pulverizer to crush the waste EPDM into 0.5-2mm particles, and then separate the fiber material through airflow to ensure that the purity of the recycled material is ≥95%. After that, the EPDM recycled powder is mixed with the new material, and a new EPDM sheet is generated again through an extruder at 180-200℃ and 10MPa pressure.
The price of general waterproof EPDM membrane is $2.5-6.0/square meter. The price of EPDM sheet for roof is $4.20-14.25/square foot. The price of industrial sealing EPDM sheet is $10-15/square foot.
Weprofab’s EPDM sheet meets the certifications of NSF 61, ASTM D2000, FDA 21, UL 94 V-0, EN 681-1, ISO 9001, GB/T 20671.
