Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by Dr John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1] . Its manufacture employs the same method today.
1 wrz 2019 · Low Density PE (LDPE) is created as a result of free-radical polymerisation which results in the formation of a mixture of short- and long-chain PE branches.
1 sty 2024 · Introduction. Medical devices ranging from structures providing physical support and improving mobility such as knee implants to more life-saving devices such as pacemakers are used to augment the functionality and enhance the quality of human lives.
Applications in the healthcare industry and medical devices in particular, have some demanding requirements for thermoplastic materials that are unique to this arena.
13 maj 2022 · Thermoplastics (a type of plastic) are recyclable since you can melt and shape the plastic polymers as much as possible. Therefore, unused parts during manufacturing can be reused. This reduces wastage of materials and improves cost-effectiveness. 7 Types of Common Thermoplastics in Medical Injection Molding.
Linear low density polyethylene is a copolymer of ethylene and other alkenes such as butene, hexene or octene. This results in an essentially linear chain arrangement, with the comonomer (i.e. the butene, hexene or octene) forming short, regular chains on the main carbon backbone.
Our Purell LDPE, HDPE and PP resins are widely used by customers to produce items such as surgical devices, diagnostic devices, products used to treat or assist in the treatment of disease, injury or handicap, as well as drug delivery systems by injection, inhalation, topical application or oral administration.
