The Many Types Of Polyurethane And What They Are Used For – TPC

When you’re looking to reduce the weight of packaging parts, polyurethane is the go-to material on your dunnage needs. It may be custom-made to the form of any merchandise for safety and cushioning. Polyurethane packaging foam (PPF) is used to bundle gadgets like fragile glass and delicate electronics. PPF is versatile, cost-effective, and customizable.

Sealant Depth & Backing – In joints wider than ½” (12mm) but not exceeding 2″ (50mm), the sealant depth should be maintained at ½” (12mm) at the center of the joint (for traffic functions see Pecora Technical Bulletin #104). – For joints wider than 3″ (76mm), a mechanical preformed joint system such as Pecora Dynaspan (visitors applications) or preformed silicone profiles similar to Pecora Silspan (architectural applications) ought to be thought of. – Acceptable sealant backing equivalent to a backer rod put in at 25% compression should be utilized so as to control sealant depth. A compressed, tight match of the backer rod is critical so as to attenuate backer rod movement which may improve the possibility of sealant slump.

Joints between precast concrete sections are typically linked utilizing a cementitious grout. Grout is a mixture of water, sand, and cement that’s mixed and may reach compressive strengths of 6,000 to 10,000 psi at 28 days of curing. Usually cementitious grouts are used to bed the joints between precast sections or to facilitate a structural reference to projecting reinforcing steel embedded into a pipe sleeve. Whether making a bed of grout or pumping the grout into open cavities between precast sections, the joint must be prepared to take away all dirt, oil, grease, and other free material that could prevent a strong bond with the grout. The joints should then be carefully aligned, joined collectively, and any excess grout that squeezes out can be wiped away.
