3M MP+ Fire Barrier Moldable Putty Stix
3M MP+ Fire Barrier Moldable Putty Stix is a one-part, re-enterable, intumescent putty that putty can quickly form to firestop through penetrations and blank openings in fire-rated assemblies. We formulated this dark red, easily moldable putty stick to provide up to 4 hours of fire protection. When used in a penetration firestop application, this firestop putty intumesces in the annular space to surround the penetrant, helping prevent the spread of fire, smoke, and toxic gas before, during, and after exposure to a fire. In addition, this product helps minimize sound transmission through assemblies requiring an STC rating and acts as a draft and cold smoke seal for systems with L-Ratings.
3M MP+ Fire Barrier Moldable Putty Stix is typically used to seal gaps between cables in multiple penetrations and is suited for numerous firestop applications, including cable (including inner fiber duct and cable). Insulated pipe; Electrical Conduit; Metal Pipe; Penetration against air draft, smoke, toxic gas, and flame propagation. These putty stix also produce a breeze and cold smoke seal and help reduce noise transfer.

Question & Answers
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
