FDA AND FOOD CONTACT
FDA approval confirms an adhesive or sealant is safe to use where it may indirectly contact food, such as in packaging or food processing equipment. It's based on FDA rules, CFR (Code of Federal Regulations) 175.105, that set out which ingredients are approved for this use. Some products meet an even stricter standard (21 CFR 175.300) for situations involving more prolonged food contact.
For the full list of FDA approved adhesives and sealants contact the TECHSiL Technical Team.

BIOCOMPATIBILITY
Biocompatibility is demonstrated by two main tests used to show a material is safe for contact with the human body: USP Class VI and ISO 10993-5. USP Class VI is a US standard that checks a material doesn't cause harmful reactions when it encounters tissue. ISO 10993 is the international equivalent and covers areas like skin irritation and toxicity.
TECHSiL offer a range of products with biocompatibility approval which are suitable for medical device applications.

REACH AND ROHS
REACH and RoHS are EU rules limiting harmful chemicals in products. REACH requires manufacturers to track and disclosure substances of high concerns. RoHS bans specific hazardous substances in electrical and electronic products. The bulk of REACH and RoHS compliant products TECHSiL supply are polyurethane elastomers and foams for entertainment, automotive and prototyping applications via our sister site BJB Materials Europe.
For REACH/RoHS compliant foams and polyurethanes visit our sister site BJB Materials Europe.
UL CLASSIFICATION - UNDERWRITERS LABORATORIES
UL (Underwriters Laboratories) is a well-known independent safety testing organisation. ‘UL Approved’ is not a formal approval and can relate to many different tests, however for adhesives and sealants it usually refers to having UL-94 and UL 746 T1 approvals for flammability and electrical application suitability.
UL-94 is for flammability testing and is used frequently for appliance and electrical equipment. It rates materials based on how well it stops burning once a flame is removed. V-0 is the highest rating, meaning vertically self-extinguishing, and HB being the lowest (Horizontal burn)
UL 746 is for materials used in electrical applications involving temperature and exposure to thermal stress.

GAS AND WATER
The Gas Industry Approvals confirm suitability for both combustible gas for fuel and gases for respiration in medical treatment. Approval organisations include BAM, DVGW and KIWA.
The Water Industry Approvals confirm suitability of the adhesive products for sealing and contact with potable drinking water and for sealing and contact with sewage and wastewater. Approval organisations include NSF, WRAS, and WRC.
For Permabond adhesives which meet gas and water approvals visit our sister site GlueOnline.
SUSTAINABILITY
Sustainability related approvals cover recyclability, biodegradability, and the us of harmful chemicals. These are especially important in the packaging industry and for PPWR.
PFAS free means a product contains no per- and polyfluoroalkyl substances which are long lasting, manmade chemicals being increasingly restricted by regulators due to environmental and health concerns.
ASTM D6400 - The standard used to confirm a plastic material will fully break down in an industrial composting facility, without leaving anything toxic behind.
EN13432 - European equivalent of ASTM D6400, it confirms packaging or material will break down safely and completely in an industrial composting facility.
ASTM D6954 - This standard tests plastics that are designed to break down through a mix of exposure to oxygen/sunlight and natural biological action.
ASTM D6866 - This test tells you how much of a material's carbon comes from plants or other renewable sources, it's how biobased content claims like "30% plant-based" are verified.

FLAMMABILITY, FIRE, AND SMOKE
EN 45545 is the European fire safety standard for materials used in rail applications. It sorts materials into three levels, HL1, HL2, and HL3, based on factors such as time spent in tunnels, whether the vehicle is automatic, double decked, or has sleeping accommodation, and sets requirements covering flame spread, smoke and toxicity.
TECHSiL EN 45545 compliant materials cover Plexus adhesives and certain 3M tapes.
