For decades, asbestos was a widely used material across numerous industries due to its exceptional heat resistance and insulating properties. However, the severe health risks associated with airborne asbestos fibers, including asbestosis, lung cancer, and mesothelioma, led to its ban or strict regulation in most countries. The primary danger lies in the inhalation of microscopic, dust-like fibers released during the handling, cutting, or degradation of traditional asbestos-containing materials (ACMs). In response to the critical need for safer alternatives that retain beneficial properties, advanced material science has developed a new category of products: Dust free Asbestos. These are not the asbestos of the past, but innovative, engineered materials designed for safety and performance.
At Kaxite, we have dedicated years of research and development to perfecting our line of high-performance, non-hazardous insulating materials. Our proprietary Kaxite Secure-Seal Technology ensures that any potential fibers are permanently encapsulated within a resilient polymer or cementitious matrix. This fundamental innovation results in a product that handles like a conventional industrial material but without generating the dangerous respirable dust associated with legacy asbestos. Our dust free asbestos solutions provide peace of mind for engineers, contractors, and facility managers, enabling them to meet stringent safety regulations without compromising on thermal efficiency, fire protection, or durability.
Choosing Kaxite’s dust-free asbestos materials offers a multitude of benefits over older, hazardous materials and even some modern alternatives.
Kaxite offers a range of dust-free asbestos products tailored for specific applications. Below are the detailed specifications for our flagship product line, the Kaxite Thermo-Shield Series.

What exactly is "Dust free Asbestos"? Is it still asbestos?
Kaxite's dust free asbestos is an advanced engineered material. It utilizes chrysotile or other mineral silicates that are permanently encapsulated within a proprietary binding matrix. The "dust-free" designation means the product is engineered and tested to prevent the release of respirable fibers during handling, cutting, and throughout its service life. It is a safe, non-friable alternative designed to replace hazardous legacy materials.
How does Kaxite ensure the product is truly dust-free?
Our Secure-Seal Technology is a multi-stage process. First, selected fibers are treated with a stabilizing agent. They are then uniformly dispersed and locked within a high-density polymer or inorganic cement binder during manufacturing. Every production batch undergoes rigorous testing using phase-contrast microscopy (PCM) and transmission electron microscopy (TEM) to verify that fiber release is below detectable limits, far exceeding OSHA's permissible exposure limits (PELs).
Is special training or PPE required to install Kaxite materials?
For general handling and installation, standard personal protective equipment (PPE) such as safety glasses, gloves, and a NIOSH-approved N95 dust mask is sufficient for nuisance dust, as per standard workshop practice. This is a significant advantage over legacy asbestos, which requires full containment and respiratory protection. We always recommend following our installation guidelines and local safety regulations.
Can Kaxite dust-free asbestos be used for high-temperature gaskets?
Absolutely. Our KX-TS200 product is specifically engineered for gasket and sealing applications. It maintains excellent compression recovery and seal integrity at continuous temperatures up to 500°C. Its non-friable nature means it can be cut to precise shapes on-site without creating a hazardous work environment, unlike traditional compressed asbestos sheets.
How does the thermal performance compare to traditional asbestos or other modern insulations?
Kaxite Thermo-Shield products offer thermal conductivity comparable to high-quality traditional asbestos insulation, often with improved efficiency due to our engineered matrix. When compared to some synthetic alternatives, our materials provide superior fire resistance and dimensional stability at extreme temperatures, making them ideal for demanding industrial applications.
What is the lifespan of Kaxite dust-free asbestos products?
When installed according to our specifications, Kaxite materials have an exceptionally long service life. They are resistant to degradation from heat, moisture, and most chemicals. We offer a standard 10-year warranty against material failure, but in many static applications, a lifespan of 25+ years is achievable with proper maintenance.
Is this product approved for use in my country/region?
Kaxite products are manufactured to comply with major international standards. We maintain a database of regional approvals and certifications, including CE marking for Europe and compliance with ASTM standards for North America. Please contact our technical support team with your location and application details for specific certification information.
How do I dispose of off-cuts or old Kaxite material?
Due to its non-friable, dust-free nature, waste from Kaxite products is typically classified as non-hazardous solid waste in most jurisdictions, unlike hazardous waste from legacy asbestos removal. However, disposal regulations vary by locality. We provide a Material Safety Data Sheet (MSDS) that classifies the product for transport and disposal. Always consult and comply with local waste management regulations.
Can it be used in marine and offshore environments?
Yes, several Kaxite products, particularly the KX-TS300 boards and KX-TS400 cement, are highly resistant to saltwater corrosion and humidity. They are widely used for insulation and fireproofing on ships, oil rigs, and in coastal industrial facilities.
Does Kaxite offer custom shapes or sizes?
Yes. While we supply standard sheets, boards, and powders, our production line can accommodate custom pre-fabricated sections, molded shapes, and specific dimensional cuts to reduce on-site labor and waste for large projects. Contact our project engineering team for details.
