Parker offers a broad selection of hydraulic pumps designed for various applications, from low-pressure mobile equipment to high-pressure industrial machinery.

Silicones, semiorganic polymers composed of silicon atoms interspersed with oxygen atoms and methyl groups attached to the silicon atoms, exhibit a basic polymer structure known as polydimethylsiloxane.

Performance testing was conducted on the cured product of the epoxy matrix resin in this embodiment, cured at 120 °C for 2 hours, using the methods and parameters recorded in specific embodiment 1. The test results are as follows:

The core-shell polymer is composed of a soft core of polybutadiene rubber and a hard shell of polymethyl methacrylate.

WynCoat® is our brand of silicone-based agents, polydimethylsiloxane modified-PDMS for painting and inks.

Silicone coating leveling agents are additives used in paint and coating formulations to improve the uniformity and smoothness of the applied film. They work by reducing surface tension gradients within the coating, which helps to minimize surface defects and achieve a more consistent appearance.

Pest management is a critical aspect of crop production, requiring careful consideration to ensure effective control while minimizing harm to crops, humans, and the environment. In this pursuit, the use of pesticides often encounters barriers such as waxy cuticles on plants and protective exoskeletons on insects.

Polyesters are versatile polymers formed from a combination of dicarboxylic acids and diols. Their diverse applications depend on their production method and the resulting molecular arrangement.

Anti-scratch, abrasion-resistant, and slip additives find applications in various industries and products where protection against scratching, wear, and slipping is desired. Here are some common applications:

The fundamental structure of organic silicone resin comprises two main components: polysiloxane and organic polymer. This hybrid material inherits the qualities of both pure silicone resin and organic resin.

Release coatings are used to create non-stick surfaces on various substrates, enabling easy separation of adhesives, foods, and other materials. Emulsion release coatings and silicone release coatings are two common types of these coatings, each with distinct properties, advantages, and applications.

WynPUF® is the brand name for polyurethane foam additives, with XH-2950 being a specialized silicone surfactant designed for flexible foam applications.

WynCoat* SE-4251 is a specialized additive designed to enhance the performance of both water-based and solvent-based coating systems. It is an 80% active dispersion of a very high molecular weight polydimethylsiloxane (PDMS) gum, renowned for its beneficial properties in various industrial applications.

The main chain of organosilicon is highly flexible due to its basic geometric molecular structure. The intermolecular forces between its molecules are much weaker compared to similar compounds, resulting in lower viscosity, weaker surface tension, lower surface energy, stronger film-forming ability, and excellent anti-adhesion and demolding properties.

Silicone surfactants are essential components in the production of high resilience (HR) foam, particularly polyurethane foam. They offer several advantages and applications due to their unique chemical properties. Here are some of the key applications of silicone surfactants in high resilience foam:

Zhejiang Xinan Chemical Industrial Group Co., Ltd. (known as Wynca Group) was established in 1965, and listed in Shanghai Stock in Sept. 2001.

Silicone resin boasts exceptional properties, including heat resistance, cold resistance, moisture resistance, hydrophobicity, and weather resistance. As a result, it is widely utilized in the special coatings industry, particularly as a base for silicone coatings

Silicones are semi organic polymers consisting of silicon atoms alternating with oxygen atoms with methyl groups attached to the silicon atoms. The basic polymer structure is polydimethylsiloxane.

Superfine fiber synthetic leather, often referred to as microfiber leather or synthetic suede, is known for its soft texture, durability, and versatility. The additives used in its production can enhance its properties, such as softness, breathability, and resistance to wear and tear.
