In the fields of aerospace, new energy, electronics and semiconductors, there is a material that can be called an "extreme environmental guardian"——Thermoplastic polyimide（TPI）Through its multiple advantages such as ultra wide temperature resistance range, high-strength mechanical properties, and strong insulation, it has become the "key password" for upgrading high-end products.
On this track long dominated by international giants, Jiangsu Junhua Special Polymer Materials Co., LtdJSJHTPI-02 molding powderby virtue ofraw materialThe full chain technical support and precise performance control from aggregation to sheet customization have enabled domestic TPI to achieve'Available'toVery usefulLeap forward and become the preferred brand trusted by the industry.
Why has TPI become a "hot commodity" for high-end materials?
Being able to establish a foothold in high-end manufacturing, TPI's "all-around strength" is not accidental. The stable aromatic heterocyclic units in its molecular structure endow it with properties far beyond ordinary engineering plasticsHardcore characteristics.
JSJHTPI-02 molding powder is suitable for compression molding, and the above figure shows the specific measured indicators of the product
01Amazing temperature resistance span
JSJHTPI-02 molding powder has achieved stable service in the extreme temperature range of -269 ℃ to 250 ℃. Whether in extremely cold environments or high temperature conditions, there will be no brittle cracking or deformation problems, and its performance is always reliable.
02Mechanical strength fully stretched
JSJHTPI-02 has a bending strength of 160MPa, a bending modulus of up to 3.1GPa, a Rockwell hardness of 122HRR, wear resistance and impact resistance, and is not easily worn out after long-term use. The tensile strength reaches 118Mpa, the tensile modulus is 3.1Gpa, and the product has high toughness.
03Excellent insulation performance
JSJHTPI-02 has a dielectric constant of 3.4, a volume resistance of 10-16 at 23 ℃, and can provide a strong safety barrier for electronic devices.
04Safe, environmentally friendly and reliable
JSJHTPI-02 has strong self extinguishing ability, low smoke emission rate, and is stable and non-volatile in high temperature, high vacuum, and irradiation environments, making it suitable for strict environmental requirements.
These features makeJSJHTPI-02Mold powder has become an "irreplaceable material" in fields such as aerospace components, new energy equipment, precision electronics, and special medical devices, directly determining the performance limit of end products.
From performance to the entire chain, the advantages are visible and tangible
There are many TPI products on the market, but there are few brands like Junhua that can accurately match international standards and have full chain independent advantages. Based on years of experience in researching and manufacturing special polymer materials, Junhua TPI's core advantages are hidden in every performance detail.
01Full chain independent and controllable, quality built from the source
asPEEK、 Junhua, a professional manufacturer and service provider of PI high-performance plastics, has completed research and development as well as pilot scale production in the workshop. The product performance indicators are stable, the price is reasonable, and the supply is stable and guaranteed. Connecting the entire chain from raw material research and development to finished product delivery is the core confidence for stable product quality
●Self developed core technology:Relying on years of technological accumulation, independently controlling the TPI powder polymerization process, controlling the molecular structure and molecular weight distribution from the source, ensuring consistent performance of each batch of products, and avoiding batch differences;
●Strict quality control system:The entire production process follows high standard testing, from raw material purity to mechanical and dielectric properties of finished products, every indicator is traceable, and the yield rate ranks among the top in the industry;
●Large scale production capacity guarantee:Build a professional PI workshop,JSJHTPI-02The production line can meet the stable delivery of large orders and also undertake customized needs, with a delivery cycle 20% shorter than the industry average, avoiding customer "waiting anxiety".
02Scene depth adaptation, multi domain implementation verification
The advantages of JHTPI-02 molding powder ultimately depend on practical application. With precise performance control, it has taken root in multiple high-end fields:
●aerospaceUsed for high-temperature resistant wire insulation layer, lightweight structural components, stable operation in extremely cold high altitude and high temperature conditions, with minimal volatile matter and no pollution to precision instruments;
●New energy:Suitable for high-voltage motor insulation components, battery seals, temperature and voltage resistance, helping equipment improve safety and service life;
●Precision Electronics:As a core material for high-frequency components and flexible electronics, its low loss and strong insulation characteristics ensure stable signal transmission;
●Special industries:Used for bearings and seals under high temperature conditions, wear-resistant and radiation resistant, reducing equipment maintenance costs.
Choosing Junhua as the material is more than just reliable
Under the wave of "domestic substitution",JHTPI-02 molding powderNot only did it break the price monopoly of international brands, but it also won market recognition with its practical performance and service.
From every precise data of materials, to a fully autonomous and controllable production system throughout the entire chain, and to successful implementation cases in multiple fields, Junhua has always been committed toIntegrity, pragmatism, cooperation, innovation, and win-win outcomesAs the core, providing for customersOne stop service from material selection to application solutions.
If your product is facing severe challenges such as high temperature, extreme cold, high pressure, and strong radiation, you need a PI material with stable performance and reliable quality,Junhua CorporationIt's definitely your best choice.
