Resin-treated compressed wood laminates, also known as Compregs have been one of the most advanced concepts of engineered wood technology. They are made by placing both wood veneer or fibers under high pressure with thermosetting resins then there comes a product with high strength, durability, and resistance to moisture and chemicals. Compregs have been used widely in industries such as construction, furniture making, and chemical processing industries where the high performance of the compregs is appreciated.
In India, the Bureau of Indian Standards (BIS) has laid down the Quality Control Orders (QCOs) for any product such as compregs to maintain quality and safety standards. This process also makes a positive impact on the recognition of consumer trust, as well as opens doors for manufacturers in the marketplace. With industries shifting toward sustainability and better performance, compregs are gaining attention and recognition for use in highly dependable and robust applications. This blog is going to offer detailed information about the manufacturing processes, performance criteria, testing techniques, and BIS certification of resin-treated compressed wood laminates, which are some of the most necessary materials in the present industrial world.
BIS Registration Sample
Resin-treated compressed wood laminates (compregs) are engineered compressed wood laminates that are made from compounding layers of wood veneer or fiber that are bonded with a thermosetting resin under pressure and heat. This process improves the performance densities of the wood to mechanical properties and physical, chemical, and moisture resistance. When based on Compregs, the key functions of tendonsβdimensional stability and resistance to environmental effects β are remarkable, so these materials are used in an enormous number of applications: construction, furniture, and chemical industries.
The nature of compregs depends on the components of wood fibers and synthetic resins in their composition. The resin also plays the role of a filler by infilling porous spaces in the wood fibers then forms a stiff matrix that enhances the mechanical properties of the material. This makes compregs appropriate for uses in which normal wooden materials cannot stand the rigors of the environment.
The manufacturing process of resin-treated compressed wood laminates involves several key steps:
This manufacturing process guarantees compregs with improved mechanical characteristics and strength for use in a wide range of applications.
To ensure that resin-treated compressed wood laminates meet industry standards for performance, specific requirements must be adhered to:
Performance testing for compregs typically includes:
Determines the extent to which the material can take the tensile load on it.
Estimates the characteristics of the laminate with the view of determining the resistance to bending forces.
Aluminium tri-hydrate also preferably monitors the amount of moisture absorbed over time.
This involves placing samples in contact with definite reagents with an aim to determine certain changes in properties.
These tests help to verify that compregs have adequate characteristics in terms of safety and performance needful for their specific use.
To conduct testing on the Resin treated compressed wood laminates (compregs) β For chemical purposes effectively, laboratories must adhere to specific requirements:
Labeling and markings are fundamental requirements of BIS standards regarding specifications for Resin-treated compressed wood laminates (compregs)β For chemical purposes. Each product must include:
The following are the given documents for BIS Certification:
| General Documents | Technical Documents |
|---|---|
| Business License | Plant Layout |
| Trademark License | List of Manufacturing Equipment |
| Application Form | Manufacturing Process Flow Chart |
| Authorization Letter | Product Literature |
| Laboratory Test Reports | List of testing equipment and machinery |
| MSME certificate | Productβs technical Specification |
| List of calibration certificate |
The BIS certification process for Resin treated compressed wood laminates (compregs) β For chemical purposes involves several steps:
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that the manufacturers need to understand so that they can get an efficient certification process.
Importance of BIS Certification
BIS certification is crucial for several reasons:
Conclusion
Compressed wood laminates or compregs produced from resin-treated laminated compressed woods are another step twist in engineered wood composite technology that produces increased durability and chemical resistance that could be applied to many applications. Due to the implementation of the Quality Control Order by the body of International Standardisation (BIS) in India, it has become mandatory for manufacturers to meet the required performance standards and go through a very essential certification process. This not only makes the product achieve the required quality but also serves the interest of the consumer because those products that do not meet the required standards do not find their way to the market. In their new forms, compregs are poised to take on more significant roles in industries that are moving to higher, safer, and better quality territories with positive impacts on the manufacturing sector in India.

Great services provided by Professional Utilities. They are best in this industry and the best part is their prices are so affordable. Kudos to you. Now you guys are my full-time consultant.
Aftab Alam
Compregs are products of wooden veneer or fiber laminates glued and pressed, by means of thermosetting resins at high temperatures and pressures.
It also refers to the Testing and Certification scheme of BIS that establishes that the products conform to the safety and quality requirements prescribed by Indian laws to create consuming public confidence.
Compregs are used in construction, furniture production, car parts, units, and chemical storage applications.

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
