An isocyanate-terminated Urethane elastomer film (IPOTM; MW− = 1350 g/mol) was used to modify silica nanoparticles (SNPs). The nanoparticles were spherically coated by an organic shell consisting of the polyether material with 55% by weight, according to thermogravimetric analysis (TGA).
IPOTM diisocyanate, as a telechelic Urethane elastomer films , was also used for the preparation of polyurethane elastomers (PUEs) through polyaddition reactions with 1,4-butanediol in the presence/absence of IPOTM-modified SNPs.
The elastomers were characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and field emission-scanning electron microscopy (FE-SEM).
Despite the use of the low amounts of the organically modified filler (5.0 and 7.0 wt.% of OSNPs), a significant enhancement in the storage and loss moduli (E’ and E” values) of the Urethane elastomer films could occur.
Also, according to the tan δ vs temperature graphs obtained from dynamic mechanical analysis (DMA), the IPOTM-modified SNPs led to a little decrease, up to 5°C, in the glass transition temperatures (Tg values) of the elastomers.
In addition, TGA thermograms showed that no reduction occurred in the thermal stability of the elastomeric polyurethanes after the addition of IPOTM-modified nanoparticles.
The Global Urethane elastomer films market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Urethane elastomer films come in a variety of hardnesses. A Durometer is the measure of the hardness of a particular material. Most elastomers are measured on the Shore A Hardness Scale for durometers.
American Polyfilm offers Urethane elastomer films that measure from 70 to 95 on the Shore A Durometer Scale. Higher durometer grades yield a very tough product with high puncture and abrasion resistance and excellent chemical resistance.
Lower durometer grades exhibit a supple quality and feel soft against human skin, making it an ideal product for medical applications.One of Polyurethane Film’s most desirable qualities is its elongation capabilities. Some of American Polyfilm offers films are able to withstand over 600% elongation before breaking.
Urethane elastomer films also have excellent memory, meaning it will return to its original dimensions after being stretched.Polyurethane Film has excellent low temperature flexibility.
Most Polyether TPU products retain their flexibility even when exposed to temperatures as low as -60ºF, easily outperforming PVC and making it a perfect material for demanding environments.
