A primer on material testing rubber
The purpose of performing material testing is to ensure the
properties of the materials will meet specific requirements.
Proper testing on a material testing/force stand ensures that the
material will respond appropriately when placed under the expected
usage conditions, or meet the standards required for
product development. For rubber materials, the properties are
often found by testing the raw component before it is made into
the final product.
Tubing die reconfigures internal chambers
Guill Tool has achieved a series of successes in the areas of multi-layer dies and, most recently, a reciprocal tubing die for wound draining that reconfigures the internal chambers of the tubing to accommodate drainage. Drain tubes can be inserted prophylactically to prevent or remove the accumulation of fluid in a wound. Alternatively, such tubing can also be therapeutically inserted to evacuate an existing collection of fluid in a wound.

UK researchers introduce degradable bonds into thermoset polymers for easier recycling
Researchers made a series of polymer gels with breakable bonds incorporated into different parts of the structure, and tested whether the properties changed after the gel was degraded and reformed.
The researchers hope this model system can be applied to other types of polymers, including adhesives, sealants and elastomers.
Bangladesh Forest Research Institute (BFRI) introduces three high-yield rubber varieties
The Bangladesh Forest Research Institute (BFRI) has introduced three groundbreaking rubber varieties—RM 001, RM 002, and RM 003—to address persistent challenges in the country’s rubber industry.
With locally cultivated rubber trees experiencing low latex yields, these varieties have the potential to transform commercial rubber farming in Bangladesh.
The genesis of this breakthrough lies in BFRI’s long-term mission to revive the dormant rubber industry. Cloned from high-yielding rubber trees in Malaysia, the newly developed varieties thrive in two soil types—sand and loam—and require minimal fertilization.
