PEI plastic is characterized by high intensity, high rigidity, abrasion resistance and dimension stability.PEI plastic is a transparent solid of amber, which has inherent flame retardancy and low smoke intensity without adding any additives. The oxygen index is 47% and the combustion level is ul94-v-0.
PEI plastic is 1.28 ~ 1.42 g/cm3 density, glass transition temperature is 215 ℃, thermal deformation temperature of 198 ~ 208 ℃, can use for a long time under 160 ~ 180 ℃, allows intermittent maximum temperature of 200 ℃
PEI plastic has excellent mechanical strength, electric insulation, radiation resistance, high and low temperature resistance and fatigue resistance and molding processability;The addition of Glass Fiber, carbon fiber or other filler can enhance the modification purpose.
3. Production:
Polyether ether ketone plastic sheet (PEEK plastic sheet),
Antistatic polyether ether ketone plastic sheet (ESD PEEK plastic sheet),
Conductive polyether ether ketone plastic sheet (CON PEEK plastic sheet),
Polyether ether ketone plastic rod(PEEK plastic rod),
Antistatic polyether ether ketone plastic rod(ESD PEEK plastic rod),
Conductive polyether ether ketone plastic rod (CON PEEK plastic rod),
Polyetheretherketone (PEEK) plastic is a kind of excellent performance of special engineering plastics, has more significant advantages compared with other special engineering plastics..Can be used for high-end technology such as mechanical, nuclear engineering and aviation.
Advantage :
1)Excellent chemical resistance and hydrolysis resistance
2)Excellent physical and mechanical properties
3)Resistance to high temperature is 260 degrees,
4) light and good dimensional stability
5 )excellent flame retardancy
6)Good electrical insulation and electrical stability
7 )it can be mixed, easy to process composite
8)Good self-lubrication
4. Production:
polyphenyl ether plastic sheet(PPO plastic sheet ).
PPO plastic is a special kind of Engineering Plastic, which has many features that other engineering plastics do not have:
1. Transparency: PPO plastic is one of the few transparent plastics;
2. Non-toxic: PPO plastic itself is less toxic and more suitable for food and medical applications;
3. Low temperature resistance: the low temperature of the PPO in the low temperature of minus 170 degrees centigrade, which is a lot of engineering plastic;
4. Low gravity: 1.08 g/cubic cm is slightly more dense than water;
Main features of Advanced Plastic
Heat temperature of 150 ~ 300 ℃
Advantages :
1).Good in heat resistance,
2).Good chemical resistance and radiation performance,
3).Good flame retardancy
4).Good stiffness, strength, toughness, creep, abrasion and other comprehensive mechanical properties.
Application: space aviation, defense military industry, nuclear power, electronics, transportation, machinery manufacturing, medical devices and other civil fields.

1. Collision compatibility shaft diameter and bearing bushes are straight to touch and avoid the seizure. The function of constituting the gap is smooth. The data elements that affect the compatibility of conflict and sub-collision are: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
.1) The difficulty of forming alloys by metallurgical materials.
.2) Affinity of materials and smoothing agents.
.3) The conflict factor of the pair of data in the absence of smoothness.
.4) Microscopic arrangement of data.
.5) Thermal conductivity of the data.
.6) The size of the data surface and the characteristics of the oxide film.
2. The clamped data allows the external hard particles to be clamped in the smoothing agent to avoid scratching or (and) wear of the abrasive particles. For metal data; low hardness and low modulus of elasticity; clampability is good; Non-metallic materials are not required; for example, carbon graphite; low modulus of elasticity; but the clamping is not good. NTN bearings generally use softer data and harder data to form a conflicting width; generally use softer materials as bearing pads.
3. The running-in property is in the running-in process of the shaft diameter and the bearing bush; the shaft diameter and the bearing bushing error, the coaxiality error, and the appearance roughness parameter value are reduced; the touch is uniform; then the ability of the conflicting force and the wear rate is lowered.
4. The conflict compliance data relies on the elastoplastic deformation of the surface to compensate for the initial cooperation failure function of the sliding conflict. The data with low elastic modulus is better.
5. Wear resistance is the ability of the auxiliary data to resist wear. Under regular wear conditions; wear rate or wear degree, the reciprocal of wear amount to indicate wear resistance.
6. Anti-weariness The ability of data to resist fatigue damage under cyclic loading. At the operating temperature; the strength, hardness, impact strength and arrangement uniformity of the bearing material are very important for the fatigue. The wear-in and clamping data are good. Generally, the resistance to fatigue is poor.
7. Corrosion resistance data resists the ability of corrosion. Smooth oil will gradually oxidize when used in the atmosphere; acidic substances occur; and extreme pressure additives are also contained in most smooth oils; they all corrode NTN bearing data; thus; NTN bearing data requirements With corrosion resistance.
8. The state in which the cavitation resistant solid moves relative to the liquid; when the bubble in the liquid breaks near the solid appearance; the partial impact high pressure or part of the high temperature occurs; the cavitation wear will be incurred. The data against the cavitation wear is called gas resistance. Corrosion. General; copper-lead alloy, tin-based NTN bearing alloy and aluminum-zinc-silicon alloy have good cavitation resistance.
9. Compressive strength accepts unidirectional loads without being crushed or the scale does not change.
