Chemical resistance film metallized polyester film that is bi-axially oriented and has great chemical resistance, high barrier (otr & mvtr) qualities, and high metal bond strength.
particularly good machinability. Applications requiring ethyl acetate resistance can use the product. In laminates for sauces, tomato ketchup, liquid juices, hot fill milk powder, tea, coffee, bag in box, cosmetics, and personal care goods as a high barrier metallized layer.
Appropriate for many flexible packaging formats, including web form feed, flat pouches, stand-up pouches, etc. Constant lamination interlayer bonding strength. Various flexible packaging formats, such as web form feed, flat pouches, and stand-up pouches, produce laminates.
The Global CHEMICAL RESISTANCE FILM market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Based on proprietary PVOH resin and formulation technology, Sekisui Chemical Co., Ltd.’s High Performance Plastics Company (whose president is Naofumi Negishi) has created a harsh chemical resistant water-soluble film.
By using this film, packaging waste will be reduced and chemicals that need to be handled carefully can be handled easily and safely. As soon as the film is ready, samples will be made accessible.
They intend to focus on emerging packaging markets in Japan and abroad that utilise the distinct traits of harsh chemical resistance, such as those in disinfection, sterilisation, insecticides, and chemicals, etc (halide chemicals in particular).
To start product sales production is still moving forward. Sekisui Chemical High Performance Plastics Company and Sekisui Film Co., Ltd. of the Group will be primarily in charge of overseeing sales (whose President is Takeshi Inoue). Markets will be developed both domestically and abroad.
Creation of a Two-Component, Chemical-Resistant Polyurethane Coating System Due to their superior tactual sensing properties and high durability, two-component (2K) polyurethane (PU) coatings are frequently employed in electrical device applications and vehicle interiors. These coating applications have called for a variety of functionalities.
For instance, in recent years, there has been a lot of focus on the chemical resistance of coatings to cosmetics, sunscreens, and repellents. It is common knowledge that some additional chemicals, such as UV absorbers, have an impact on the performance of PU coatings. Standard 2K PU coatings made of acrylic-urethane resins are frequently insufficient to stop swelling or peeling brought on by chemical attacks.
It has been discovered as a result that the newly created coating systems can significantly enhance both chemical resistance and adherence to plastic substrates. Comparing the polyol systems to traditional coating systems, the impacts of the polyol systems on the flexibility, impact resistance, and hardness of the coating film were also examined.
The appearance of the coating film before and after dropping test solution, which is composed of equal weights of 3-(4-Methoxyphenyl)-2-propene acid-2-ethylhexyl ester: UV absorber (Tokyo Chemical Industry Co., Ltd.), 3,3,5-Trimethylcyclohexyl Salicylate: UV absorber (Tokyo Chemical Industry Co., Ltd.), and N, N-Diethyl-m-toluamide (Tokyo Chemical Industry Co., Ltd.)
The substrate was an ABS plate. Two locations on the coated film surface received drops of the test solution at a density of about 0.05g/cm2. The test sample was baked for four hours at 80 °C. The test sample was cleaned using paper towels after being taken out of the oven.For the adhesion test, the ABS plate and the PC plate were both used.
According to ISO 2409: 2013, the test technique for adhesiveness to ABS and PC (Cross-cut test). The film’s characteristics were assessed using the following techniques: the bend test using a cylindrical mandrel (ISO 1519: 2011), the quick deformation test for impact resistance (ISO 6272-1: 2011), and the evaluation of film hardness by pencil test (ISO 15184: 2012). For these evaluations, the sheet steel served as the substrate.
