We would like to introduce the "Durability Promotion Test" conducted by Ronbic Co., Ltd. To verify the durability performance required in actual applications (such as weather resistance, light resistance, humidity and heat resistance, heat resistance, etc.), evaluations are conducted at each stage: before promotion, during promotion, and after promotion. Testing can be performed not only on test specimens but also on actual products and parts. 【Examples of Durability Performance】 - Weather resistance - Light resistance - Humidity and heat resistance - Heat resistance, etc. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Heat Cycle Test" offered by Ronbic Co., Ltd. As a reliability evaluation of plastics, tests are conducted under high temperature and high humidity using a constant temperature and humidity chamber to assess the degradation of resin samples. Evaluation methods include appearance assessments such as color evaluation, as well as mechanical property evaluations like tensile and bending tests. We also accommodate various evaluations before and after the heat cycle test. 【Constant Temperature and Humidity Chamber Conditions】 ■ Temperature Range: -40℃ to +100℃ ■ Humidity Range: 20 to 98% RH ■ Heating Rate: 2.0℃/min ■ Cooling Rate: 3.0℃/min ■ Chamber Dimensions: 630mm × 400mm × 900mm (Width × Depth × Height) *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Super Accelerated Weather Resistance Testing Machine <SUV: Metal Halide Lamp Type>" handled by Ronbic Co., Ltd. The testing method involves continuous light exposure and cycle operation (light exposure, condensation, rest). The ultraviolet irradiance is 1500W/m² (300–400mm) and can be adjusted. Utilizing high degradation acceleration, it can be used for screening tests of long-term weather resistance performance as a preliminary study. 【Control Range】 ■ Temperature Control Range - During irradiation: 50–85°C (Black panel thermometer at room temperature 20°C) - During rest: 35–75°C (Black panel thermometer at room temperature 20°C) ■ Humidity Control Range - During irradiation: 40–70% RH (Black panel thermometer at 63°C) - During rest: 50–90% RH (Black panel thermometer at 50°C) *For more details, please download the PDF or feel free to contact us.

On our company website, we introduce "Weather Resistance Testing and Degradation Analysis Examples" through physical property measurement and evaluation. The sample is ABS resin, and the weather resistance test was conducted using a Sunshine Weather Meter (SWOM), analyzing the situation where degradation progresses from the surface to the interior. Additionally, using TEM images (cross-sectional observation) before and after the SWOM test, it is explained that degradation of the butadiene rubber (domain) component in ABS was observed more prominently at the surface. [Contents Included] ■ TEM Images (Cross-sectional Observation) ■ Microscopic Infrared Absorption Spectra (Measurements at Different Depths) *For more details, please refer to the related links or feel free to contact us.

The "Long-term Durability Test (Creep Test)" is an evaluation of the long-term durability of resin materials, assessing creep characteristics under tensile, bending, and compression modes. By varying the load stress (weight) and measuring the time until failure for each, it is also possible to predict the lifespan of the resin material by plotting these results. Creep failure refers to the phenomenon where a resin material experiences failure below its breaking strength when subjected to a load for an extended period. [Test Conditions] ■ Test Temperature: 23℃ to 200℃ ■ Test Load: 1 to 500 kg ■ Test Modes: Tensile, Bending, Compression ■ Number of Tests Possible: Up to n = 6 *For more details, please refer to the related links or feel free to contact us.
