Hydrophobic Polymers

Hydrophobic polymers, also known as water-repellent polymers, are substances that do not dissolve in water or other polar solvents. This category encompasses various materials, including acrylics, epoxies, polyethylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, polydimethylsiloxane, polyesters, and polyurethanes. Our hydrophobic polymers serve multiple roles as coatings, adhesives, fibers, films, and engineering plastics. Moreover, they find extensive application in the biomedical field, contributing to functions like vascular grafts, implants, drug delivery, and ophthalmic applications.

With our comprehensive collection of hydrophobic polymers, categorized based on their chemical composition and monomer attributes, advancements seem closer than ever before.

ACRYLIC POLYMERS

Acrylic polymers encompass a range of polymers derived from acrylic, acrylonitrile, acrylamide, and maleic anhydride. These homopolymers and copolymers exhibit diverse characteristics such as rigidity, flexibility, hydrophilicity, or hydrophobicity. Most of these polymers fall under the thermoplastic category, allowing them to be easily shaped through thermal processes. As a result, they find widespread use in applications involving polymer coatings, adhesives, and fibers.

ETHER POLYMERS

Ether polymers contain ether groups within their main molecular chain. They tend to be pliable and contribute impact resistance to bulk properties. Many polyethers possess functional groups at their chain ends, making them valuable in the production of higher molecular weight polymers. This characteristic also classifies them as macromonomers, frequently utilized in the formulation of polyesters and polyurethanes. Notably, this category includes polymers and oligomers of poly(propylene glycol) (DOWANOL®).

FLUOROCARBON POLYMERS

Fluorocarbon polymers are exceptional due to their resistance to being wetted by either hydrophilic or hydrophobic substances. They demonstrate remarkably low coefficients of friction, coupled with exceptional chemical and thermal resistance. While copolymers of fluorocarbon polymers can be more easily processed in a molten state compared to pure poly(tetrafluoroethylene).

POLYSTYRENE POLYMERS

Polystyrene and its copolymers have made significant strides as films, foams, and structural components. Copolymers containing diene monomers undergo cross-linking to enhance physical properties and generate thermoplastic elastomers. Polystyrene film boasts high transparency to visible light and a notable refractive index.

POLY(VINYL CHLORIDE) POLYMERS

Poly(vinyl chloride) (PVC) is often highly plasticized to enhance its rheological properties during melt processing. It is particularly susceptible to degradation from UV exposure and elevated temperatures, leading to the addition of stabilizers.

POLY(N-VINYLPYRROLIDONE) (PVP) POLYMERS

Poly(N-vinylpyrrolidone) (PVP) stands as a polar polymer characterized by excellent film-forming capabilities and adhesion properties. It is frequently used in formulations for hair sprays, hand creams, and in the textile industry due to its affinity for various dyes. PVP is also a biocompatible polymer that has seen usage as a substitute for blood plasma, although this application is becoming less common.
