摘要： EPM and/or EPDM compositions exhibiting superior green strength as compared to conventional EPM/EPDM compositions are attained by adding, along with the rubber curing agents and various conventional additives as desired, colemanite and/or alumina trihydrate. Colemanite, alumina trihydrate or a mixture of the two have unexpectedly been found to enhance the green strength of EPM/EPDM compositions prior to vulcanization. The green strength promoters of this invention utilized in EPM/EPDM rubber compositions allows for faster mixing (shorter mixing cycles) and improved processing rates, such as faster calender throughput rates, to be achieved.

摘要： An outdoor enclosure for air handling equipment is adaptable to accept add-on air handling equipment by virtue of a two-position cover panel. The cover panel has a generally rectangular shape and is attached to a side panel of the enclosure. The cover panel is selectively mountable in either a vertical position to cover a fresh air opening through the side panel or in an open position to uncover the opening. The cover is opened by pivoting it about its upper horizontal edge which is located just above the opening and swinging its lower edge outwardly away from the side panel. An add-on mist elimination filter is installed in a generally horizontal position betweeen the cover panel's lower edge and the lower edge of the side panel's opening. In the open position, the cover panel serves as a rain sheltering hood over the filter while the opening allows fresh outside air to be drawn into the suction side of a fan located inside the enclosure. The two-position cover panel facilitates the conversion of the enclosure while minimizing the need for special, single-purpose panels.

摘要： Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention. The improvement comprises admixing from about 0.5 to about 10.0 parts per hundred rubber (phr) of bis(2-mercaptobenzothiazato) nickel with a vulcanizable rubber composition prior to combining the metal and rubber and then curing. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and metal member includes the step of dispersing from about 0.5 to about 10.0 phr of nickel in a vulcanizable rubber composition prior to curing.
