Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
Plastic is the generic name for a family of synthetic materials derived from petrochemicals. It is often product of two or more components. It is often product of two or more components. There are many families of plastics and polymers being used in construction industry, such as acrylics , composites , expanded polystyrene , polycarbonates ...
Twinwall plastic most commonly refers to two exterior plastic sheets that are connected with a plastic support layer to create parallel channels. This design adds both impact toughness and the ability to support weight. Twinwall plastic may also be used to describe a pipe that has a smooth interior with exterior air filled ridges. [3]
Seagrass, used in coastal areas where there are estuaries such as Scotland. Has a longer life than straw. Claimed to have a life in excess of 60 years. Rye straw, commonly used in a barn. Raffia palm leaves; a well organised raffia palm leaves is mainly used as roof houses in Nigeria, especially among the Igbo. Rice straw, commonly used in ...
Plastic consumption uses by field. Filler materials are particles added to binders (resin, thermoplastics, cement) to make a composite material. Filler materials improve specific properties or make the product cheaper. [1] Coarse filler materials such as construction aggregate and rebar are used in the building industry to make plaster, mortar ...
The polymers used as plasticizers exhibit surfactant properties. They are often ionomers bearing negatively charged groups ( sulfonates , carboxylates , or phosphonates ...). They function as dispersants to minimize particles segregation in fresh concrete (separation of the cement slurry and water from the coarse and fine aggregates such as ...
Two carcinogenic chemicals used in cleaning products and other common household goods have been banned in the U.S., the Environmental Protection Agency (EPA) announced in a Dec. 9 press release ...
The petrochemical industry has been trying to save itself by attempting to rapidly expand demand for plastic products worldwide (i.e. through pushbacks on plastic bans and by increasing the number of products wrapped in plastic in countries where plastic use is not already as widespread (i.e. developing nations)).
