BAIJIAN - Third party testing organization
Polyurethane elastomer is a high-performance elastomer、 also known as polyurethane rubber、 which is a type of elastic polymer material that contains a large number of amino ester groups (NHCOO) in the molecular chain. From a molecular structure perspective、 polyurethane is a block polymer、 generally composed of flexible long chains of oligomers and polyols、 forming soft segments. The hard segments are composed of diisocyanates and chain extenders、 and the hard and soft segments are intermingled to form repetitive structural units. In addition to containing amino ester groups、 polyurethane elastomers also contain ether、 ester、 or urea groups. Due to the presence of a large number of polar groups、 hydrogen bonds can be formed within and between polyurethane molecules、 and micro phase zones can be formed between soft and hard segments、 resulting in micro phase separation. Even linear polyurethane can form physical cross-linking through hydrogen bonding
Testing cost: It needs to be determined based on factors such as qualification requirements and testing items. The third-party testing agency of Baijia.net will arrange engineers to communicate with you and provide a quotation while confirming the plan
The processing cycle for testing reports is usually 3-10 working days、 depending on the testing project.
. In addition、 if there is an urgent need within the feasible range、 additional arrangements need to be explained to the engineerFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific、 fair、 and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsinspection and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered、 meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing、 with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle、 low cost、 and attentive service 7. Possess authoritative qualifications such as CMA、 CNAS、 CAL、 etc 8. The testing report is authoritative and effective、 and is generally used in China
