It is difficult to combine these properties in a well-balanced manner; for example, chemical resistance tends to deteriorate significantly, and weather resistance also tends to deteriorate significantly.

In addition, its practical durability is unsatisfactory, and it cannot withstand practical use under relatively harsh conditions. In addition, by omitting (iv) an elastomer selected from the group consisting of acrylic elastomer and MilS elastomer in the composite elastomer component, it is possible to combine the excellent properties of the present invention in a well-balanced manner. It is similarly difficult, for example, the internal hydraulic rupture property decreases markedly at #ll temperature,
In addition to a tendency to decrease in heat resistance, there is also a significant deterioration in the severity and durability of the steel, resulting in a result that is completely unsatisfactory for practical use under relatively harsh conditions.

Therefore, in the present invention, it is essential to use a composite elastomer component consisting of the above (iii) and Gy), and the mouth contact of both of these elastomer components is the above (D

The mechanism of action of the individual components in the multi-component system M11, which requires these four components, on the composition is unknown, but it is possible to As shown in one example, this was a completely unexpected result that could not have been expected based on the knowledge of the prior art that impact resistance can be improved by adding an elastomer.

Furthermore, in the composition of the present invention, the above-mentioned four-component system H11 combination exhibits excellent low-temperature ramming resistance, excellent internal hydraulic pressure fracture resistance at room temperature, and (1) X11-chemical resistance. In order to best provide a unique YXM property with a well-balanced combination of heat resistance, excellent heat resistance, excellent weather resistance, and excellent practical durability, the combination of the above four components and their relative proportions should be used. This is an important factor.

After 2 weeks of continuous soaking under these conditions, it begins to rot, and after washing the red and wiping off the moisture on the surface with a dry cloth, immediately put it in the market.>
l' and (Ji') are weighed on a scale, and the increase in the number of ova on the test piece from the immersion treatment compared to the test piece before immersion is shown in percentage. A value of several liters indicates poor chemical resistance, and a value of several liters indicates poor chemical resistance.

In addition, I! I! The appearance of the subsequent test piece is inspected with the naked eye, and changes in appearance are judged according to the following evaluation criteria.

li+No discernible change compared to before immersion treatment.

2nd class! Slight discoloration is observed.

Grade 3: Discolors to brown.

Grade 4 8 Discolors to blackish brown.

Grade 5 2 Discoloration to blackish tone and sweating phenomenon observed.

The lower the grade value, the better the chemical resistance.

(Force resistance M (ability test).

A test piece cut out from the pipe to a size of 1cWL x 2cm was subjected to a load of 5ft.

Tested according to JIS KT206C (Vicat Softening Point Test Method for Thermoplastic Plastics), and the Vicat softening point (°C) is measured and shown. The larger the value, the better the heat resistance.

(6) Weather resistance test.

(e-1) W-0-MC Weatherometer) 10
Charpy test after 0 hours.

A test piece made by cutting a test tube into a pipe length of 1 ocr/L is used. After the test piece was irradiated for 100 hours with a weatherometer that sprayed the black panel at a temperature of 63 ± 2 ° C for 18 minutes at 180 minute intervals, a Charpy impact strength test piece was cut from the treated test piece.

(a) Practical durability test.

Chlorine gas at 40°C to 60°C is supplied through a test pipe with a length of 5 tn. For testing, pipes are installed outdoors, and
The pipe was used as the above-mentioned gas supply pipe for the long-term test of copper for one year from mid-August to mid-August of the following year. After the test was completed, a 5-meter test pipe was cut from near the center of the test tube, and the tail temperature was 25°.
At C, 10 yap/mi from the circumferential direction of the pipe
The amount of deformation of the pipe when it is compressed and destroyed at a speed of n (
crn) was actually measured.

The amount of deformation (cm 2 ) of the pipe is determined from the difference between the length of the pipe before the compression test and the e-beam length at the time of failure, and the amount of deformation with respect to the length of the pipe before the compression test is expressed as a batch rate. Deformation amount is 50%
In the above cases, evaluate without destroying.

The larger the deformation value, the better the practical durability.
