Vicat Softening Temperature Of Plastics Is The Temperature At Which A Standard Flat-ended Indentor Penetrates One Millimetre Into The Surface Of The Material Under Test Under A Specified Load. The Test Is Conducted By Placing A Test Specimen Taken From The Sample Under Test On A Flat Platform Inside A Liquid Bath And Applying Compression Load Over Its Upper Face Through A Flat-ended Indentor. The Load Is Applied By Placing Dead Weights On The Upper End Of The Indentor. After The Test Specimen Attains The Temperature Of The Bath, The Bath Temperature Is Increased Gradually Till The Indentor Penetrates By Exactly 1 Mm Into The Test Specimen. The Bath Temperature In Degrees Centigrade At Which This Happens Is Reported As The Vicat Softening Temperature Of The Sample Under Test.
The Globe Vicat Softening Temperature Apparatus For Plastics Consists Of A Hinged Metallic Frame Which Serves As Support For The Test Specimen. The Frame Is Fitted With A Bush For Guiding A Rod With A Hardened Indenting Tip At Its Lower End And A Loading Platform Near Its Top To Place The Weights On. A Dial Gauge Is Fitted At The Upper End Of The Frame To Measure The Movement Of The Rod.

Designed for Versatile Laboratory Applications
Suitable for laboratory testing of plastic softening points, the Vicat Softening Point Apparatus accommodates a range of test conditions. Its adjustable test width, stroke, and specimen capacity make it adaptable for various research and quality control needs across exporters, manufacturers, and suppliers. Consistent performance is ensured up to 85% relative humidity and in ambient temperatures reaching 300C.
FAQ's of Vicat Softening Point Apparatus:
Q: How does the Vicat Softening Point Apparatus determine the softening point of plastics?
A: The apparatus uses a controlled heating process, applying either a 10 N (1 kg) or a 50 N (5 kg) load on plastic test specimens while monitoring the temperature digitally. The softening point is identified when the specimen exhibits a specified deformation under the standard test conditions.
Q: What are the specimen requirements for conducting tests on this equipment?
A: Each test requires two specimen samples with dimensions of 1010 mm and a thickness between 4 to 6 mm. This ensures compatibility with the apparatus and delivers accurate results according to standard laboratory protocols.
Q: When is it recommended to use the Vicat Softening Point Apparatus in laboratory settings?
A: The apparatus should be used when precise softening point measurements are needed for plastic materials, especially during research, quality control, or product development phases in manufacturing and exporting sectors.
Q: Where can the Vicat Softening Point Apparatus be installed within a facility?
A: It is designed for benchtop mounting in laboratory environments, providing stable support and easy access for technicians performing material softening tests.
Q: What is the process for performing a softening point test with this apparatus?
A: First, position the specimen and select the appropriate load. Set the temperature range (from 50C to 300C) via the digital display, and initiate the test at a speed of 50 mm/h. The apparatus continuously monitors and records specimen deformation and temperature until softening occurs.
Q: How does the apparatus benefit laboratory professionals and manufacturers?
A: It offers precise, reproducible measurements with high accuracy and immediate display of results, ensuring reliable quality control and research data for plastics development and compliance with industry standards.
