Automobile antifreeze, as an important medium in the engine cooling system, protects the normal driving of the car all the time

Industry problems
Industry problemsHowever, among all auto parts, there is one application that still cannot use nylon single 6 to replace nylon 66, which is the part in the cooling system mentioned above
.
Material Features: More than just hydrolysis resistance
Material Features: More than just hydrolysis resistance More than just hydrolysis resistanceThis is a brand-new PA6/PP alloy modified material.
Through the introduction of polyolefin molecular chain groups, the major properties of nylon materials are optimized:
Higher dimensional stability while improving water and moisture absorption
Greatly improved flow performance
Impact performance is enhanced
Enhanced chemical resistance
Lower density and lower cost per part
The price of PA6 substrate is cheaper than that of PA66, and the comprehensive cost reduction can reach more than 20%
rigorous testing
rigorous testingDifferent OEMs have different definitions for testing hydrolysis-resistant materials, including coolant type, temperature and soaking time
.
Among the German top three test standards above, AKRO's new hydrolysis-resistant PA6 material has passed the tests of VW and BMW:
Test results from VW
Test results from VWAccording to VW's test standard for hydrolysis-resistant materials, after completing the whole cycle, the remaining value of flexural strength must be ≥25MPa
.
It can be seen from the test results that both AKROMID® PA6 GF30 HR and PA66 GF30 HSLR, which has been approved by VW, passed the test, but the residual flexural strength of AKROMID® PA6 GF30 HR is much higher than the required 25MPa, and its hydrolysis resistance is better.
Excellent
.
Test results from BMW BMW
Test results from BMW BMWAccording to BMW's hydrolysis-resistant material testing standards, after completing the entire cycle, the remaining tensile strength, tensile modulus, flexural modulus and elongation at break of the material were tested
.
Overcome difficult problems and bid farewell to leakage risks
Overcome difficult problems, say goodbye to leakage risks , say goodbye to leakage risksEven for the hydrolysis-resistant modified PA66 material, after soaking in high-temperature ethylene glycol coolant, the surface cracking phenomenon is a historical problem that cannot be solved
.
AKROMID® PA6 GF30 HR developed by AKRO has no cracks on the surface after immersion in coolant at 135°C for 3000 hours, which completely solves the industry problem

DPPD free
DPPD freeWhat is DPPD
DPPD, chemical name: N,N'-diphenyl-p-phenylenediamine, is often used as an additive in the polyamide (commonly known as nylon) industry for hydrolysis resistance and aging resistance
.
The safety of engineering plastic components used in the automotive industry is regularly checked in accordance with the REACH directive
.
DPPD has recently been classified as a high-risk ingredient, so this would mean that polyamide-based materials with a DPPD content of more than 0.
1% would need to be declared
.
DPPD-free hydrolysis-resistant nylon
DPPD-free hydrolysis-resistant nylonThe hydrolysis-resistant polyamide materials of AKRO-PLASTIC engineering plastics have been widely used in the coolant-resistant applications of passenger cars, trucks and special vehicles for a long time.
In response to the updated regulatory requirements, we have developed a hydrolysis-resistant DPPD-free Polyamide based material including this hydrolysis resistant PA6 GF30
