Biowool marine blanket is a kind of low biological persistence and hydrophobic inorganic alkaline soil silicate fibre product made from silica, calcium and magnesium raw materials. It is degradable in human body fluids and completely harmless to human body. It has the properties of fire prevention, heat preservation and sound insulation.It is a pure inorganic environmental protection soluble material.It is widely used in Ro-Ro passenger ships, offshore platforms and other ship types requiring weight reduction.
1.Compliance with the requirements of 2010 FTP code on fire resistance test procedures for non-flammability and A-level separation.
2.Meeting IMO SOLAS Security Convention, HSC Security Rules, EU Directive 2014/90/EU.
3.Ensure the safety of ships and crew and increase the safety of fire prevention.
4.Improve comfort cabin living, improving the working environment at sea.
Environmentally friendly
Biowool marine blanket has been tested in mice and has certain degradability in human body fluids. It belongs to exemption and non-restriction category (non-carcinogen) in the European Union 69/97/EC carcinogen safety classification, and has passed the EC and EUCEB.
Safe and effective fire performance
Refractoriness > 1580 ℃ , pure inorganic refractory fibers, with excellent fire resistance, stable temperature resistance, fire protection grade is: A1 class non-combustible materials.
No flue gas
Pure inorganic fibers, needle-punched interwoven moulding, without any organic adhesives. In case of fire, smoke-free generation, completely non-flammable.
Waterproof
Biowool marine blanket can realize single fiber and integral waterproofing according to customer's demand, and the product can not absorb water when placed in water.
Soft texture
The 100% whole fiber component is produced by needle-punched interweaving process, which guarantees the flexible material of the product and is easy to construct.
Lightweight single square
Light density, thin thickness and light weight per square can greatly reduce the weight of the hull and make it lighter.
Sound effects
According to GB / T 20247-2006 standards, testing Biowool blanket thickness of 50mm, the bulk density of 64 and 96 of sound-absorbing, noise reduction coefficient as follows.

1.Soft, no need to soften in complicated place, easy to install according to the structure
2.Node structural light weight, reducing the use of insulation material, increasing the net loads
3.Install in roll form, high efficiency for installation
4.No need to fix by rivet in Stiffener place
5.Insulation material in thin depth and light weight, saving space
No gap in products joint; one lay installation, easy and fast; two lays insulation, good structure and good sound insulation result; break joint, gap space of two blanket should be more than 150mm; use diameter 3mm rivet and diameter 30mm locking plate to fix; space of rivet 300mm to 350mm, rivet length should be 10mm to 15mm more than insulation thickness. The interspace under stiffener was filled in fiber blanket since it is soft. Use more full roll blanket instead of piece.
