More than 50 years manufacturing resins
Ercros began its operations in the field of resins in 1969 as the group Formaldehído y Derivados, S.A.
Over the course of more than 50 years, we have continuously innovated this family of products, enhancing both their properties and their sustainability. Technological advancements driven by our R&D and Engineering departments have enabled us to offer an extensive portfolio of high-performance industrial resins.
Key application sectors include wood and furniture, insulation, and the impregnation of paper, as well as mineral or synthetic fibers. Our portfolio comprises phenol-formaldehyde, urea-formaldehyde, melamine-formaldehyde, melamine-urea-formaldehyde, and modified melamine-formaldehyde resins.
Ercros provides complete adhesive systems for these resins, including hardeners, additives, and formaldehyde scavengers.
We have also developed new resins, which are featured under our ErcrosGreen+ and ErcrosTech brands:
- The ErcrosGreen+ brand encompasses resins manufactured using a new technology that reduces formaldehyde emissions by 90% compared to previous levels, achieving ultra-low levels comparable to those found in natural wood. These resins were developed entirely by the R&D department of the intermediate chemicals division—based at the Tortosa plant—and comply with the strictest standards and recommendations for the construction sector in Europe, the United States, and Japan. They also offer an added benefit in terms of sustainability, as they are derived from the most sustainable raw materials.
- Under the ErcrosTech brand, we offer a range of high-performance technical products that provide customized solutions for every application. These products are tailor-made and designed to meet the specific needs of each client.
ErcrosGreen+ resins
What are they used for?
The ErcrosGreen+ family includes a wide range of resins and adhesives that are mainly used for wood and furniture manufacturing; insulation; and impregnation of paper, mineral and synthetic fibres. Each variety of resins is especially suitable for the following specific applications.
Urea-formaldehyde (UF) resins:
- Particleboard and plywood
- Laminating
- Impregnation
- MDF
Melamine-urea-formaldehyde (MUF) resins:
- Moisture-resistant particleboard
- Fibers
Melamine-formaldehyde (MF, modified MF) resins:
- Laminating
- Impregnation
- Postformable laminates
- Superplasticizers
Phenol-formaldehyde (PF) resins:
- Plywood
- Fiber impregnation
- Paper impregnation
They offer excellent adhesion to wood and can be formulated using raw materials from renewable sources
Ercros offers urea-formaldehyde (UF) resins—specifically LEF (low formaldehyde emission) and ULEF (ultra-low formaldehyde emission) grades—that comply with European standards E0 and E1/2, as well as the California Air Resources Board (CARB) standards, phases 1 and 2.
Due to their high reactivity, low cost, and excellent adhesion to wood, UF resins are used for:
- For the manufacture of particleboard: boards are produced for interior applications (furniture, cabinets, doors, and insulation) that meet strict emission standards, such as class E0 or CARB Phase 2.
- For the manufacture of plywood: plywood panels are produced for wall, ceiling, and floor coverings, as well as for furniture and cabinets; their very low formaldehyde content allows them to comply with strict CARB Phase 2 emission standards.
- For lamination: paper impregnation processes are used to create laminates with a very low formaldehyde content.
- For impregnation: UF (urea-formaldehyde) resins are used to produce molding powders for the manufacture of a wide range of products with very low emissions.
- For the manufacture of fiberboard: very low-emission fiberboard (MDF) is produced, which complies with the most stringent regulatory standards.
At the client's request, the formulation can incorporate raw materials from renewable sources, thereby contributing to the development of a material with a lower carbon footprint.
Urea-Formaldehyde (UF) resin varieties and characteristics
LEF: low emission formaldehyde; ULEF: ultra low emission formaldehyde; y CARB: California Air Resources Board, phases 1 and 2.
Melamine-formaldehyde resins are resistant to humidity
Melamine-formaldehyde (MF) resins are used to manufacture LP flooring laminate and natural laminate. Ercros has MF resins classified as LEF (low emission formaldehyde).
MF resins are the most suitable resins for achieving high resistance to humidity, for which they are used:
- In laminating: to obtain laminated boards for kitchens and bathrooms with very low formaldehyde emissions.
- In impregnation: MF resins are used to obtain moulding powders for the manufacture of tableware and kitchen utensils that comply with the strictest standards.
Varieties and characteristics of melamine-formyl resins (MF)
LEF: low emission formaldehyde; ULEF: ultra low emission formaldehyde; y CARB: California Air Resources Board, phases 1 and 2.
Phenol-formaldehyde resins are stable and water resistant
Ercros has phenol-formaldehyde resins (FF) classified as LEF (low emission formaldehyde), ULEF (ultra low emission formaldehyde) and ULEF/CARB (California Air Resources Board), phases 1 and 2.
The high stability and water resistance of FF resins provide very interesting properties for manufacturing plywood, impregnating glass and polyamide fibre, and fire-retardant laminate. In particular:
- In plywood: to manufacture plywood boards for interior applications, with humid environments or in aggressive exteriors (such as marine board), as they comply with the E0 standard.
- In laminate: due to its low content of free formaldehyde.
- In fibre impregnation: due to its low free formaldehyde content.
Varieties and characteristics of phenol formaldehyde resins (PF)
LEF: low emission formaldehyde; ULEF: ultra low emission formaldehyde; y CARB: California Air Resources Board, phases 1 and 2.
