UNITIKA Nylon 6
UNITIKA nylon 6 resins have a variety of properties.
It is important to understand the basic properties of resins and use them correctly in producing molded products.
Here in this page, the mechanical, thermal and electrical properties of UNITIKA nylon 6 resins are described, mainly focusing on A1030JR (high cycle) and A1030GFL (30% glass fiber-reinforced) resins.
(1) Mechanical Properties
Mechanical properties of materials are quite important. The properties of nylon resins vary according to the temperature, water content, and others. Therefore, it is important to know in advance how the resins may change according to these factors.
The relationships between tensile strength and water content, and between tensile strength and temperature are shown in Figures 1 and 2. (Test method: ASTM)

Bending properties are also important factors in designing products, and the bending properties are also affected by temperature and water content, like tensile strength. In Figures 3 and 4 are shown the relationships between bending properties and water content; and in Figures 5 and 6, between bending properties and temperature. (Test method: ASTM)

The impact strength is quite important when the products are used as mechanical parts. The impact strength suffers greater influence from water content and temperature than other mechanical properties. The relationships between impact strength and water content and between the impact strength and temperature are shown in Figures 7 and 8. (Test method: ASTM)

A phenomenon that the deformation of a product gradually increases over time under a certain load is called the creep phenomenon. The creep properties are important factors to be considered in designing products that may be exposed to stresses for an extended period of time. Tensile creep curves are shown in Figures 9 and 10.
