Propolis Propolis Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures, it becomes hard and brittle. While foraging, worker bees primarily harvest pollen and nectar,
Speed glue Butterfly's Bryce FX, Joola's Samba, will absorb the glue more readily and therefore have a bigger dome when they expand, leading to a greater effect, with harder sponges e.g. most Chinese rubbers, Butterfly's Bryce Hard, expanding less leading to a slightly lesser effect. In gameplay terms, speed glue has some disadvantages. Due to the increased sponge thickness, speed does increase, but as mentioned before usually control decreases as speed increases. Also, after several regluings speed glue begins to build up on the racket, increasing the weight of the paddle. The nature of table tennis blades are so sensitive, that a
