- the conditions for the low-temperature impact test were as follows: After leaving the resin tube specimen in an atmosphere of -40 ° C for 5 hours, two types of weights, each weighing 450 g and 900 g, were placed in the same atmosphere at a height of 30 Omm. From the test piece, and the presence or absence of cracks was visually determined. ⁇ indicates that no cracks occurred, and X indicates that cracks occurred.
- the resin tube made of polyamide 11 resin without a plasticizer as shown in Comparative Example 1 is vulnerable to impact. It can be seen that the material itself is not a resin having high impact resistance.
- (B) a resin tube polyamide 1 1 composition of the components 25 to 35 weight 0/0 embodiment it can be seen that the impact resistance is remarkably improved. As in Comparative Example 5, when the proportion of the polyamide 11 composition increases, the impact resistance performance decreases.In Comparative Example 4, the outermost layer is made of a polyamide 11 resin containing a conventional plasticizer. The impact resistance of the tube (Comparative Example 2) does not change.
- the test results confirm that the thinner the layer is, the thinner it is expected to be, and the weaker it is to impact.However, the thicker the layer, the better. It turns out that the range of mm is good.
- the conventional resin tube mainly composed of polyamide 11 resin or polyamide 12 resin cannot be obtained while using polyamide 11 resin as a base resin. Impact performance can be obtained.
