PRODUCTS | Basics of Acrylic Elastomer
NOXTITE is acrylic elastomers (ACM) developed through the chemical synthesis
and rubber polymerization technologies of UNIMATEC.
NOXTITE® with its well-balanced heat and oil resistance, is used in seals, gaskets and hoses in automobiles, contributing to enhance reliability and safety. NOXTITE also has the effect of imparting elasticity and flexibility as an adhesive raw material - NOXTITE is utilized in wide range of industries.
Characteristics of NOXTITE
Key properties
- ・Its wide temperature range from -40 °C up to 185 °C enables your products to maintain long-term reliability over a broad temperature range.
- ・Offers outstanding oil resistance to petroleum-based oils, engine oils, gear oils and torque converter oils even in high-temperature environments.
- ・Suitable for outdoor applications due to its excellent ozone resistance and weatherability.
Characteristics
Acrylic elastomer NOXTITE offers excellent heat resistance and weatherability due to its saturated bond in the main chain structure. It also has outstanding oil resistance because of the ester bonds in its side chain structure.
Especially, HT-ACM (high temperature ACM) has properties of less degradation over a long period, contributing to longer life of your products.
The table below shows examples of NOXTITE.
UNIMATEC offers a variety of products that meet a wide range of needs, such as heat resistance, cold resistance, among others.

* For other ACM products, please check from the following.
● Test results for the heat-resistance of HT-ACM grade for hose application (test method: JIS K 6257)
NOXTITE PA-526, the HT-ACM grade, indicates less elongation than our conventional grade after being heated for 1,000 hours at 175℃.
● Test results for compression set of HT-ACM grade for seal application (test method: JIS K 6257)
NOXTITE PA-522HF, the HT-ACM grade, indicates lower compression set even after being heated for 1,000 hours at 150℃ and kept sealability.
● Test results for cold resistance of LT-ACM grades (test method: TR 10: JIS K 6261)
The LT-ACM grades NOXTITE PA-44201, PA-42400 and PA-44300 have a good balance of cold resistance and oil resistance.
* TR: Temperature Retraction test.
A rubber test piece is streched and frozen, and then retraction (= compression set in low temperature) is measured.
