Product Description

DUPLAS A.Ş., our country's first and only cork producer, has introduced DUCORK IKM & VKM products, excellent for Sound, Vibration, and seal materials, to the construction sector under the registered brand name DUCORK. They combine the natural wonder product, cork, with the latest technology and natural rubber. DUCORK IKM & VKM products are used in thinner sections compared to alternative Sound, Vibration, and seal products and do not require any additional by-products. This significantly reduces costs. DUCORK products are 100% natural and free from carcinogenic substances. The products demonstrate 95% recovery at 50% compression and offer much greater resistance to chemicals than other insulation materials. Another typical feature of the product is its resistance to fungi and insects, making it resistant to mold formation. The lifespan of DUCORK IKM & VKM is equivalent to that of your building. Tests have proven that DUCORK IKM & VKM do not ignite in fire. They prevent noise from passing into neighboring environments. Additionally, it is an excellent choice for seals. With its excellent oil resistance properties, it is an indispensable material for the automotive industry.
