HZ info:On September 5, 2025, the 21st China International Polyurethane Exhibition (PU China 2025) concluded successfully at the Poly World Trade Center Expo in Guangzhou. As a vital global platform for communication in the polyurethane industry, this exhibition attracted numerous well-known domestic and international enterprises. It provided a concentrated display of cutting-edge technologies, innovative products, and industry application solutions in the polyurethane field. 

Among them, Quanzhou Guoyan New Material Technology Co., Ltd. (hereinafter referred to as "Guoyan Pigments"), centered around Booth No. 742, showcased a range of color paste products specifically developed for the polyurethane industry, becoming one of the highlights of the exhibition.

Guoyan Pigments primarily promoted four major categories of color paste products at this exhibition, including color pastes for polyether, color pastes for polyester, PU-specific color pastes, and polyurethane fluorescent color pastes. 

Color Pastes for Polyether

The main products in this series include super black, deep blue, sky blue, yellow, red, green, purple, and super white. Their applications are extensive, covering polyether-based products such as polyether sponges, polyether shoe materials, automotive foam, PU materials, and building materials.

In terms of performance, these color pastes exhibit perfect compatibility with polyether system materials, being specifically designed for polyether systems. They comply with the new European environmental standards. They can be used for coloring various polyether foamed and non-foamed products, making the production process cleaner and the addition more convenient. The color pastes have high fluidity, effectively preventing mechanical failures. They offer excellent dispersion, uniform color, good and vivid color intensity, and can maintain long-lasting hues and color intensity. Additionally, they are formulated with high-temperature-resistant and environmentally friendly pigments, with a grinding fineness of 15 μm or less.

Regarding color shades, basic polyether color pastes can be blended with other colors to create color pastes of any desired shade. However, since the color performance of the color pastes varies in different polyether systems, precise color matching needs to be carried out within the customer's own polyether system.

Color Pastes for Polyester

The main products also include super black, deep blue, sky blue, yellow, red, green, purple, and super white. Their primary applications are polyester-based products, such as polyester sponges, polyester shoe materials, automotive foam, PU materials, and building materials.

In terms of performance, these color pastes demonstrate perfect compatibility with polyester system materials, being specifically designed for polyester systems. They meet the new European environmental standards. They are suitable for coloring various polyester foamed and non-foamed products, ensuring a cleaner production process and easy addition. The color pastes have high fluidity, preventing mechanical issues. They offer good dispersion, uniform color, excellent and vivid color intensity, and long-lasting hues and color intensity. They are formulated with high-temperature-resistant and environmentally friendly pigments, with a grinding fineness of 15 μm or less.

Regarding color shades, basic polyester color pastes can be mixed with other colors to produce color pastes of any shade. Given that the color performance of the color pastes differs in various polyester systems, precise color matching should be conducted within the customer's own polyester system.

PU-Specific Color Pastes

The main products include super black, deep blue, sky blue, yellow, red, green, purple, and super white. Their applications cover polyurethane-based products, such as polyurethane sponges, polyurethane shoe materials, automotive foam, PU materials, and building materials. 

In terms of performance, these color pastes have good compatibility with polyurethane system materials, being specifically designed for polyurethane systems. They comply with the new European environmental standards. They can be used for coloring various polyurethane foamed and non-foamed products, making the production process cleaner and the addition easier. The color pastes have high fluidity, preventing mechanical problems. They offer good dispersion, uniform color, good and vivid color intensity, and long-lasting hues and color intensity. They are formulated with high-temperature-resistant and environmentally friendly pigments, with a grinding fineness of 15 μm or less.

Regarding color shades, basic polyurethane color pastes can be blended with other colors to create color pastes of any desired shade. Since the color performance of the color pastes varies in different polyurethane systems (polyether and polyurethane), precise color matching needs to be carried out within the customer's own polyurethane system.

Polyurethane Fluorescent Color Pastes

The main products include fluorescent red, fluorescent orange, fluorescent yellow, fluorescent green, fluorescent purple, fluorescent peach red, fluorescent royal blue, and fluorescent rose red. Their primary applications are polyurethane-based products, such as polyurethane sponges, shoe materials, automotive foam, PU materials, and building materials.

In terms of performance, these color pastes exhibit perfect compatibility with polyurethane system materials, being specifically designed for polyurethane systems. They comply with the new European environmental standards. They can be used for coloring various polyurethane foamed and non-foamed products, ensuring a cleaner production process and easy addition. The color pastes have high fluidity, preventing mechanical failures. They offer good dispersion, uniform color, good and vivid color intensity, and long-lasting hues and color intensity. They are formulated with highly light-resistant pigments that never fade, providing vibrant colors. The grinding fineness is 15 μm or less.

Regarding color shades, basic polyurethane color pastes can be mixed with other colors to produce color pastes of any shade. Since the color performance of the color pastes differs in various polyurethane systems (polyether and polyester), precise color matching should be conducted within the customer's own polyurethane system.
