What is neoprene
Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene (a foaming process). It is available for purchase either as neoprene sheets or neoprene rolls.

So, briefly what is neoprene? Neoprene is a soft, flexible, and durable synthetic sponge rubber that has the following unique features:
WATER RESISTANCE: Neoprene (rubber) sheds water like a duck, making it an ideal outdoor material and an excellent choice for surf suits, wet (diving) suits and dry suits..
WEATHER RESISTANCE: Neoprene (rubber) resists degradation from sunlight, ozone, oxidation, rain, snow, sand and dust- all weather conditions.
THERMAL AND MOISTURE INSULATION: the gas cells of neoprene (rubber) make it an ideal insulation material, most notably in wetsuits and can holders.
STRETCHABLE: Neoprene (rubber) is elastic and form-fitting; it conforms to objects/equipments of varying sizes and shapes.
CUSHIONING AND PROTECTION: Neoprene (rubber) comes in various thickness and density to absorb the shock of everyday handling (shock protection)- ideal for protective cover not only for many equipments such as cameras, cellular phones but also human body such as knee and elbow pads (braces)….etc.
LIGHTWEIGHT AND BUOYANCY: a foamed neoprene (rubber) containing gas cells and therefore is light weight and can float on the water.
CHEMICAL AND OIL (PETROLEUM DERIVATIVES) RESISTANT: Neoprene (rubber) performs well in contact with oils and many chemicals and remains useful over a wide temperature range. That is why many companies use neoprene (rubber) for protective gear and clothing, such as gloves (for food processing) and aprons.
LATEX FREE: Since neoprene is a synthetic rubber, there is no latex in neoprene- no allergy that associated with latex will be found in neoprene.
