Polyurethane (PU) Resins

Polyurethane (PU) resin is a versatile and widely used synthetic material known for its exceptional durability, flexibility, and resilience. Formulated through the chemical reaction of polyols and diisocyanates, polyurethane resin exhibits a broad range of physical and chemical properties that make it suitable for diverse applications. Its flexibility can be tailored to create soft foams or rigid structures, while its resistance to abrasion, chemicals, and weathering enhances its longevity.

Our portfolio offers a wide range of specialty chemicals to solve complex issues such as dampness, heavy water ingress, structure leakage repair, and soil settlement with ultra fine cavities. While it is challenging to resolve all issues with one product, we provide flexibility, adaptation and customization to meet the specific needs of every project.

The Many Faces of Polyurethane (PU) Resin Applications

Construction Sealants and Adhesives

Polyurethane resin is widely utilized in the construction industry as a sealant and adhesive. Its excellent adhesion properties make it ideal for bonding various construction materials, such as concrete, wood, and metals. Additionally, it serves as an effective sealant, providing durability and weather resistance in applications like joint sealing and structural bonding.

Flexible and Rigid Foams

PU resin is a key component in the production of foams with diverse properties. In the creation of flexible foams, it results in comfortable and supportive materials often used in upholstery, mattresses, and automotive interiors. On the other hand, rigid foams find applications in insulation for buildings, appliances, and refrigeration systems due to their excellent thermal insulating properties.

Coatings and Surface Finishes

The versatility of polyurethane resin extends to coatings and surface finishes. It is commonly used as a protective coating for various surfaces, providing resistance against abrasion, chemicals, and UV radiation. PU resin coatings find applications in automotive finishes, flooring, and industrial equipment, enhancing durability and aesthetics.

Elastomers and Sealings

Polyurethane elastomers, known for their resilience and flexibility, are extensively used in manufacturing components such as gaskets, O-rings, and seals. These elastomers offer excellent wear resistance and durability, making them suitable for applications in machinery, automotive parts, and hydraulic systems, where reliable sealing and flexibility are crucial.
