An aliphatic dicarboxylic acid or carboxylic acid anhydride, 5-20 parts of an aromatic dibasic acid or ester, 15â50 parts of, and 0-0.002 parts of assistant are combined to create a hydrolysis-resistant polyester. Reactivity, compatibility, and hydrolysis resistance are strong points of polyester polyol.
The adhesion strength, heat resistance, and weather resistance of a flexibly packed adhesive can all be greatly improved by adding 10â100% polyester polyol, while the adhesive's initial adhesion can also be improved.
The component by the following weight part is made: aliphatic dicarboxylic acid or carboxylic acid anhydride 20-50 part, aromatic acid or ester 5-20 part, dihydroxyl polyvalent alcohol or polyether glycol 15-50 part, auxiliary agent 0-0.002 part. This makes the hydrolysis-resistant polyester polyvalent alcohol unique.
The component by weight part is made up of the following: aliphatic dicarboxylic acid or carboxylic acid anhydride 30-40 part, aromatic acid or ester 10-15 part, dihydroxyl polyvalent alcohol or polyether glycol 20-40 part, and auxiliary agent 0.0005-0.0015 part. This makes the hydrolysis-resistant polyester unique.
Global hydrolysis resistance polyester market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The first high performance PET (polyethylene terephthalate) engineering plastic that is highly resistant to hydrolysis has been introduced by Royal DSM as Arnite A-X07455.
This ground-breaking innovation creates possibilities for significant weight and cost advantages over metal in applications for automotive engine compartments.
In automotive parts that require high dimensional accuracy, exceptional chemical resistance, and very good mechanical qualities, Arnite A-X07455 enables the substitution of metals or more expensive engineering plastics like polyphthalamides (PPA) and polyphenylene sulphide (PPS). Through light lightweight, it will allow automakers to reduce costs and increase fuel efficiency.
Targeted applications for this hydrolysis-resistant Arnite A include throttle valve bodies, sensors, air control valve housings, electronic throttle control (ETC) and exhaust gas recirculation (EGR) covers, ignition systems, and air control valve housings.
In addition to having a strong resistance to hydrolysis, the novel product has great stiffness, strength, and dimensional stability. According to ISO 527, Arnite A-X07455, which has 50% glass reinforcing, has a tensile stress at break of 200MPa.

| 1 | BASF | The expanded Ultradur HR line consists of three different models: Ultradur B4330G6HRHighSpeed, a high-mobility, laser-labeled brand with 30% glass fiber reinforcement; Ultradur B4330G10HR, with 50% glass fiber; and Ultradur B4331G6HR, the following-generation product with improved processing performance. |
| 2 | DuPont | The following generation of PBT for electrical connectors and components is hydrolysis resistant. To provide exceptional melt stability during molding, DuPont has created a new PBT hydrolysis resistance technology. In comparison to the already available PBT HR grades on the market, the new Crastin HR HFS's process flexibility enables more reliable manufacturing procedures and increases in quality. |
To address the rising need for innovative energy vehicle and automatic driving system components,BASFfurther improved its hydrolysis resistant (HR) thermoplastic polyester series.
Stress corrosion cracking is caused by an alkaline environment, and the HR trademark greatly enhances resistance to this environment. The new Ultradur B4331G6HR, which significantly enhances melt stability and fluidity, is the same.
Even at high temperatures, Ultradur B4331G6HR's viscosity did not significantly rise over an extended period of time. In order to create high-pressure plug connectors for future energy vehicles, the material can also be painted orange (RAL 2003).
A biaxially oriented polyester film composed of polyethylene terephthalate (PET) and at least one hydrolysis stabiliser chosen from a glycidyl ester of a branched monocarboxylic acid with from 5 to 50 carbon atoms, wherein said hydrolysis stabiliser is present in the film as a reaction product with at least some of the end-groups of said polyester; a process for making the same; and use of the film as a layer in polyester films resistant to hydrolysis.
Polyester films are well-known for their superior mechanical, dimensional stability, and optical qualities.Poor hydrolysis resistance is especially problematic when the film is employed in humid circumstances, at high temperatures, or in outdoor applications, such as photovoltaic (PV) cells.
Without losing the hydrolysis resistance,DuPontâsspecial combination enables a larger processing window, including the use of hot-runners and regrind. PBT with increased electrical performance is also increasingly needed for usage in automobile connectors for electric hybrid vehicles in addition to improved hydrolysis resistance.
According to OEM specifications, these connections must have exceptional color retention with heat aging and maximum CTI (600+ V) performance.Hydrolysis stabilisers are known to be included into polyester films to improve hydrolysis resistance.
Carbodiimides, for example, were recommended as end-capping agents in polyester compositions in US- 5885709 and EP-0838500, among others.However such additions have a tendency to release toxic gaseous by-products. According to US-2003/0219614-A1, the use of polymeric carbodiimides as hydrolysis stabilisers minimizes the potential for gas evolution.
Hydrolysis stabilisers selected from phenolic compounds, oxazolines, and/or monomeric or polymeric carbodiimides, optionally coupled with an organic phosphite, are taught in US-2002/0065346-A1.
The use of copper salts of organic carboxylic acids as hydrolysis stabilisers is demonstrated in GB- 1048068. US-3657191 and US-3869427 teach the modification of polyester terminal groups by interaction with ethylene carbonates or monofunctional glycidyl ethers.
