Tie Layer Resin Technologies Tie layer resins (TLR) are functionalized polyolefins that are produced by grafting anhydrides or acids to a polyolefin substrate in a post-reactor process. TLR are crucial for bonding dissimilar resins in multi-layer structures. For example, multi-layer packaging structures commonly include a non-polar polyolefin layer and a polar barrier resin layer, such…
SBS and SEBS Adhesives Technologies Styrene Block Copolymers (SBC) are synthetic polymers that have versatile properties due to their molecular structure, which is an aromatic-aliphatic combination. Styrene-ethylene-butadiene-styrene (SEBS) and styrene-butadiene-styrene (SBS) are two types of SBCs that are used in adhesives and sealants. SEBS are saturated triblock polymers that are made by hydrogenating SBS during…
Styrene Block Copolymer Technologies Styrene Block Copolymers (SBC) are synthetic polymers that have versatile properties due to their molecular structure, which is an aromatic-aliphatic combination. They exhibit excellent elastic, physical, mechanical, and processing properties. SBCs are a type of thermoplastic elastomers (TPE), sometimes called TPE-S. SBCs include styrene-ethylene-butadiene-styrene (SEBS), styrene-butadiene-styrene (SBS), and styrene-isoprene-styrene (SIS). SBCs…
