Dates: Modify . Both these compounds consist of 6 carbon molecules, which leads to name the polymer formed from them as nylon 6,6. Nylon-6 is made from a monomer called caprolactam. 2005-08-08. Other key differences between the two nylons are water absorption rates and heat deflection temperatures. monomer of nylon 66 & monomer of nylon 66 online Wholesalers - choose monomer of nylon 66 from 18 list of China monomer of nylon 66 Manufacturers. Nylon 6’s lower mold shrinkage adds reliability to final part dimensions which is beneficial whilst Nylon 66’s greater mold shrinkage, as it is exposed to cool air and solidifies, means the material’s shape changes more after processing, which must be accounted for. Nylon 6 should be used if a lightweight engineering plastic is required to withstand high impact and stress.
