OSB Types
Oriented Strand Board (OSB) is primarily made from the following types of wood:pine,poplar,Spruce,Douglas Fir.These species are commonly used because they are abundant, fast-growing, and have suitable structural properties for OSB production.
OSB Glue
PMDI Glue:PMDI adhesive is a high-performance, formaldehyde-free glue widely used in premium OSB production. It provides excellent bonding strength, moisture resistance, and dimensional stability, making it suitable for structural panels and applications that require higher durability. Compared with traditional resin systems, PMDI helps reduce formaldehyde emissions and supports better indoor air quality. However, it is generally more costly and requires stricter production control during manufacturing.
MR(Moisture Resistant):MR adhesive is a budget-friendly choice designed for interior uses. It performs well in environments with limited moisture exposure, making it ideal for dry conditions.
E2: This category allows for higher levels of formaldehyde emissions, which makes it less suitable for projects requiring stringent health standards.
E1 and E0: These classes have significantly lower formaldehyde emissions, meeting stricter health and environmental regulations. E0, in particular, is preferred for projects that prioritize minimal emissions and enhanced indoor air quality.
WBP/Phenolic Glue:For applications exposed to significant moisture or outdoor conditions, WBP and phenolic glue are the adhesives of choice. Known for their exceptional water resistance, these glues provide robust dimensional stability and durability.These adhesives are commonly used for roofing, flooring, and other moisture-prone applications.
