Is EPDM dangerous?
Both EPDM rubber, as well as waste tire crumb rubber, contain toxic chemicals and heavy metals that pose a health threat to the students who play on it. The Material Safety Data Sheet for EPDM says the product is a “Possible Cancer Hazard” – and can be an irritant to lungs, eyes and skin.
Is EPDM skin safe?
Skin Contact: Wash with soap and water. Eye Contact: Flush eyes with plenty of water. Consult a physician if symptoms persist. Ingestion: Not expected to occur during normal use of product.
What is ethylene propylene diene monomer used for?
EPDM stands for Ethylene Propylene Diene Monomer, a synthetic rubber used in a range of applications. EPDM is used most commonly used in the automotive and construction industries for various seals due to its excellent resistance to environmental factors such as Ozone, UV and general weathering.
What is Virgin crumb rubber?
Virgin crumb rubber refers to Ethylene Propylene Diene Monomer (EPDM), which is manufactured for the purpose of a sports field infill, as opposed to using rubber from recycled ground up truck tires.
Is EPDM environmentally friendly?
EPDM rubber is often hailed as the most environmentally friendly roofing system. In a report entitled “Building For The Future”, international environmental agency, Greenpeace, put EPDM membranes at the top of their rankings of low impact membranes.
Is EPDM rubber combustible?
However, EPDM is a flammable material with a very low limiting oxygen index (LOI) value, which greatly limits its further development and application [1].
How is EPDM made?
EPDM can be manufactured using one of three processes – slurry, solution, and gas-phase. – The monomers and catalyst system are injected into a propylene filled reactor in this modification of bulk polymerization. – Stabilizers and oils are added directly after polymerization (if required).
Is EPDM a food grade material?
This non-marking, non-toxic rubber is made from premium grade EPDM sheet rubber and exhibits the white color commonly associated with food-grade rubber. White FDA approved EPDM rubber is typically used for general gaskets commonly used in food processing operations.
How long does EPDM last?
50 years
EPDM roof membranes remain stable over time and can have a life expectancy of over 50 years. ** Made from synthetic rubber, EPDM roofing membranes have two primary ingredients, ethylene and propylene, which are derived from oil and natural gas.
What kind of copolymer is ethylene propylene diene monomer?
Ethylene propylene diene monomer (EPDM) is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers (3 – 9 percent) which provide cross-linking sites for vulcanization: The diene is usually dicyclopentadiene, ethylidene nobornene, or 1,4 hexadiene.
What kind of diene is used in EPDM?
The diene is usually dicyclopentadiene, ethylidene nobornene, or 1,4 hexadiene. These terpolymers can be vulcanized by traditional techniques. EPDM elastomers have excellent heat, ozone/weathering, and aging resistance.
Why does Ethylene Propylene Monomer rubber need carbon black reinforcement?
Hence it exhibits poor strength and requires carbon black reinforcement. At higher ethylene contents, say at >60%, the elastomer is semicrystalline and exhibits controllable green strength and crystallization on stretching. A higher proportion of accelerator is to be used because of low unsaturation.
What kind of solvents can EPDM be resistant to?
It is flexible above −50°C. EPDM is resistant to polar solvents such as alcohol, glycol, ketone and phosphate ester, acids, alkalis, salts, and fats. However, EPDM does not possess resistance to hydrocarbon oils and solvents.
