Drying and Heating chambers
From Testing to Trust -BINDER Solutions for Plastics and Polymers
Think of Drying and Heating Chambers as the essential climate control systems for your plastic and polymer materials. In the plastic and polymer industry, these chambers ensure that raw materials are perfectly dried and evenly heated before processing. By removing unwanted moisture, drying chambers prevent defects like bubbles and weak spots in your final products. Heating chambers, on the other hand, prepare the materials to reach the ideal temperature for molding or extrusion, ensuring smooth and consistent production. Together, these chambers optimize material performance, enhance product quality, and boost manufacturing efficiency. With reliable Drying and Heating Chambers, manufacturers can produce high-quality, durable plastic products that meet industry standards every time.

FAQ's
What are BINDER Drying and Heating Chambers used for?
BINDER Drying and Heating Chambers are precision laboratory ovens used for drying, heating, sterilising, and conditioning samples across packaging, plastics, pharma, food, and materials testing. They ensure consistent, controlled temperature environments for pre-conditioning specimens before mechanical or barrier testing, pre-drying plastic resins before processing, and performing heat ageing and stability studies.
What BINDER chamber models does Flexitest offer?
Flexitest offers four BINDER models -the M115 (natural convection), FD 56 (forced convection with APT.line™), ED 56 (advanced forced convection), and VD 56 (vacuum drying chamber). Each model is optimised for specific drying and heating applications and is available with free installation and training across India.
What is APT.line™ technology in BINDER chambers?
APT.line™ is BINDER’s patented preheating technology built into the FD 56 and ED 56 models. It preheats incoming air before it enters the working chamber, delivering exceptional temperature uniformity and fast recovery after door opening. This ensures consistent, reproducible results -critical for standardised testing and regulated laboratory environments.
What is the difference between the M115 and FD 56 chambers?
The M115 uses natural convection -heat rises gently without a fan, ideal for lightweight or airflow-sensitive samples. The FD 56 uses forced convection -an internal fan actively circulates heated air for faster, more uniform temperature distribution. Forced convection is preferred when testing multiple samples simultaneously or when rapid temperature equilibration is required.
When should the Vacuum Drying Chamber VD 56 be used?
The VD 56 dries samples under reduced pressure, which lowers the boiling point of moisture and solvents -enabling effective drying at lower temperatures. It is recommended for heat-sensitive materials, oxidation-prone samples, porous packaging materials, and solvent-containing coatings or laminates where conventional oven temperatures would cause degradation or alter sample properties.
What industries use BINDER Drying and Heating Chambers from Flexitest?
These chambers are used across flexible packaging (film and laminate pre-conditioning), plastic processing (pre-drying hygroscopic resins like PET, Nylon, ABS), pharmaceutical packaging (heat ageing and stability testing), food packaging (retort and pasteurisation simulation), paper and board (moisture conditioning before compression testing), and paints and coatings (thermal curing and ageing evaluation).
What test standards apply to Drying and Heating Chambers?
Key applicable standards include ASTM E145 (laboratory oven specification), ASTM D618 (conditioning plastics specimens before testing), ASTM D4332 (conditioning packaging components), ASTM D5374 (forced-convection ovens for coating evaluation), ISO 291 (plastics standard atmospheres for conditioning), ISO 2233 (packaging conditioning before testing), ISO 188 (rubber heat ageing), IEC 60068-2-2 (dry heat environmental testing), and DIN 12880 (electrically heated laboratory ovens safety requirements).
Why is pre-conditioning samples in a drying chamber important before testing?
Properties like tensile strength, seal strength, and barrier performance are directly affected by the moisture content and thermal history of a specimen at the time of testing. Standards like ASTM D618, ISO 291, and ASTM D4332 mandate controlled pre-conditioning before testing to ensure results are accurate, reproducible, and comparable across laboratories. Skipping conditioning is a leading cause of test variability and failed audits.
What safety and energy efficiency features do BINDER chambers offer?
BINDER chambers feature independent overtemperature protection, safety classifications per DIN 12880, door alarm systems, and optimised insulation for industry-leading energy efficiency. The APT.line™ technology minimises heat recovery time after door opening -reducing energy consumption per test cycle, lowering operating costs in high-use laboratory environments.
