Hand, luggage holder etc..With the development of high polymer material, some parts can recycle, and material is safe, easy to process
Material have increasingly been used on automotive trim.
The inside gadget of current many automobiles progressively uses TPUE (TPU) because its have it is good
Good elastomer performance and thermoplastic processing, fabulous wearability, low temperature flexibility, good physical and mechanical properties are excellent
Hydrolysis, oil resistant, solvent resistance, more important its is that one kind can be with recycling, and the material that can be degraded, to ring
Border protection has important contribution, therefore by the extensive welcome of people.
With the continuous enhancing that the growing and consumer of auto industry realizes to environment protection health, people require in-car empty
Gas is fresh, nontoxic, and quality is good.In-car volatile harmful material has attracted attention, and has caused the problem of smell
The concern of people.The source of in-car smell is many, and the volatile materials of automotive interior part is to influence in-car air
One of the main reason for quality.Macromolecule product is more and more used in automotive interior part, and what it contained has volatilization
The organic compound of property：Low molecular alkane, alkene, aromatic hydrocarbons, aldehyde, ketone material, these materials can be waved when temperature is slightly higher in the car
Uncomfortable smell is sent, results even in the uncomfortable reaction such as headache, allergy, faintness.
For odor problem, major automaker is subject to specification to these volatile harmful substances, and formulates
Relevant criterion, such as Volkswagen's VW ' s PV3900 standards, it uses 1~6 grade of evaluation, and rank is higher, and smell is got over
Greatly, could meet to require less than or equal to 3 grades；Yitong Passenger Train Co is tested using VDA 270-1992-10 standard, 1~5 grade
Evaluation criterion, rank is higher, and smell is bigger, could meet to require less than or equal to 3.5 grades, the present invention and use VDA 270-
1992-10 standard carries out test evaluation.
TPUE oxygen index (OI) is 18 or so, belongs to inflammable product, if product has a flame-retardancy requirements, such as up to
To the V-1/V-2/V-0 of UL 94 flame retardant rating, it must just add fire retardant and be modified, in order to increase fire retardant and thermoplasticity
The compatibility of polyurethane, can add some compatilizers in fire retardant, and some compatilizers can gasify volatilization at high temperature, in addition thermoplastic
Micromolecule additive in property polyurethane elastomer can equally gasify volatilization under the high temperature conditions.The gasification volatilization of small molecule can produce
Life causes product to be unable to reach requirement of the automotive trim for product odour compared with niff.
